Arthritis & Rheumatology (arthritis-and-rheumatology)

Journal positioning

Arthritis & Rheumatology (A&R) is the flagship journal of the American College of Rheumatology (ACR), publishing clinical trials, observational and outcomes research, and basic/translational science across rheumatic and autoimmune/musculoskeletal disease — rheumatoid and psoriatic arthritis, systemic lupus erythematosus, vasculitis, systemic sclerosis, Sjögren's disease, spondyloarthritis, osteoarthritis, gout, and the underlying immunology and joint/connective-tissue biology. It serves rheumatologists and autoimmune-disease scientists, and expects work that advances disease mechanism or changes how rheumatic disease is classified, treated, or monitored; underpowered single-center series and bench studies with no autoimmune/musculoskeletal-disease anchor are a weak fit. This skill is a fit / venue-selection / re-framing aid; it is not clinical or regulatory advice and does not replace the journal's current instructions for authors. Before submitting, re-check the live Arthritis & Rheumatology author instructions.

When to trigger

• The author names Arthritis & Rheumatology for a rheumatology clinical, observational, or basic/translational study and wants a fit/framing check.
• A study must be re-framed around an autoimmune/musculoskeletal-disease mechanism or a practice-relevant rheumatology question.
• The author is choosing between A&R, a general-medicine or immunology journal, and another rheumatology specialty venue.
• The author needs the journal's reporting-guideline, registration, classification-criteria, and desk-reject expectations.

Scope & topic fit

• Randomized and pragmatic trials in inflammatory arthritis, connective-tissue disease, and vasculitis, including biologics and targeted-synthetic DMARDs.
• Observational, cohort, registry, and comparative-effectiveness studies with rigorous design and confounding control.
• Disease-classification and outcome-measure development/validation (e.g., classification criteria, response indices).
• Basic and translational immunology and joint/connective-tissue biology with clear autoimmune/musculoskeletal-disease relevance.
• Imaging, biomarker, and prognostic studies with clinically meaningful rheumatology endpoints and a reference standard.
• Osteoarthritis, gout, and bone/cartilage biology with mechanistic or practice advance.

Method & evidence bar

• Clinical studies must be adequately powered with prespecified, patient-centered primary outcomes; validated disease-activity/response measures are expected, and surrogate-only endpoints need justification.
• The applicable reporting guideline must be followed and its checklist supplied: CONSORT for trials, STROBE for observational studies, PRISMA for systematic reviews, STARD for diagnostic accuracy.
• Interventional trials require prospective registration; the registration number and protocol/statistical-analysis plan are expected.
• Basic/translational claims need rigorous controls, adequate replication, and validation in patient samples or disease-relevant models, with appropriate immune/joint-assay rigor.
• Classification-criteria and outcome-measure work must follow accepted methodology with derivation and independent validation cohorts.
• Observational and registry analyses must address confounding, channeling/indication bias, and missing data; causal language must match the design.

Structure & house style

• ACR/Wiley format with a structured abstract; re-check current article types, graphical-abstract requirements, and limits on the live guide.
• The introduction frames a focused rheumatology question and its mechanistic or clinical importance; the discussion states the management, classification, or mechanistic implication plainly and uses current ACR/EULAR nomenclature and criteria.
• Tables/figures follow journal statistical-reporting standards; a CONSORT/STROBE/PRISMA flow diagram is expected where applicable; mechanistic figures must show controls and replication.
• Supplements carry the protocol, full statistical and assay methods, and additional cohorts/analyses.

Official-submission checklist

• Before giving submission-ready advice, read ../../resources/source-basis.md and ../../resources/official-source-map.md; start from the ICMJE/EQUATOR and ACR anchors, then cite the current Arthritis & Rheumatology page you checked.
• Search the live site for "Arthritis & Rheumatology author guidelines" and follow the current ACR/Wiley version.
• Re-check article types, word/figure limits, structured- and graphical-abstract format, and statistical-reporting requirements.
• Confirm trial registration, the reporting checklist (CONSORT/STROBE/PRISMA/STARD), data-sharing statement, and protocol/SAP submission; confirm use of validated outcome measures/classification criteria.
• Re-check IRB/ethics and consent, animal-use approval where relevant, ICMJE authorship and conflict-of-interest disclosure, funding, and AI-use disclosure.
• If the live official instructions conflict with this skill, the official instructions win.

Pre-submission self-check

• The study answers a focused rheumatology question with a clear mechanistic or practice/classification implication.
• The primary outcome is prespecified and patient-centered, using validated disease-activity/response measures.
• Mechanistic claims rest on adequately controlled, replicated assays, ideally validated in patient samples.
• The correct reporting checklist (CONSORT/STROBE/PRISMA/STARD) is completed and attached.
• Trials are prospectively registered with the number in the manuscript; protocol/SAP provided.
• IRB/consent, ICMJE disclosures, and a data-sharing statement are prepared; current ACR/EULAR criteria are used.

Common desk-reject triggers

• Underpowered single-center series or registry slices with no mechanistic or practice advance.
• Outcome measures that are not validated, or classification-criteria work without an independent validation cohort.
• Mechanistic claims from one model or cell line with no patient-sample validation and weak controls.
• Missing trial registration, protocol, or the required reporting checklist.
• Observational analyses with inadequate confounding/indication-bias handling or overstated causal claims.
• Basic immunology with no autoimmune/musculoskeletal-disease anchor, better served by an immunology venue.

Re-routing decision

• Allergy/asthma or type 2 clinical immunology emphasis → journal-of-allergy-and-clinical-immunology.
• Practice-changing, broadly significant trial → general medicine (jama / NEJM / The Lancet in the natural-science bundle).
• Autoimmune disease with a dominant neurology/CNS focus → brain / jama-neurology.
• Musculoskeletal imaging where the imaging method dominates → radiology.
• Pure basic immunology or matrix/bone biology with no disease translation → a basic-science venue in the natural-science bundle.
