Journal positioning

The American Journal of Respiratory and Critical Care Medicine (AJRCCM, the American Thoracic Society "Blue Journal") is the ATS flagship, publishing high-impact research across the full respiratory–critical-care–sleep spectrum and across the full evidence spectrum: definitive clinical trials and cohorts, translational mechanism, and basic pulmonary, vascular, and immunologic science. Its defining expectation is a conceptually important advance in lung biology, respiratory/critical-illness disease mechanism, or pulmonary/sleep clinical care — not an incremental single-center series or a descriptive cohort with no mechanistic or practice-changing yield. Because it spans bench to bedside, AJRCCM tolerates basic and translational work that a purely clinical respiratory journal would not. 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 AJRCCM author instructions.

When to trigger

• The author names AJRCCM or the "Blue Journal" for a respiratory, pulmonary-vascular, critical-care, or sleep-medicine study and wants a fit/framing check.
• A clinical, translational, or basic-science lung study must be re-framed around a mechanism or a practice-changing pulmonary/critical-illness question.
• The author is choosing between AJRCCM, The Lancet Respiratory Medicine (clinical/trial high-impact), and Critical Care Medicine (ICU-focused).
• The author needs the journal's reporting-guideline, registration, and basic/animal-study expectations spanning bench-to-bedside work.

Scope & topic fit

• Adult and pediatric pulmonary disease: asthma, COPD, ILD/pulmonary fibrosis, cystic fibrosis, infection, and pulmonary vascular disease (PAH).
• Critical-care and acute respiratory illness: ARDS, mechanical ventilation, acute lung injury — with mechanistic or outcome rigor.
• Sleep and circadian medicine: sleep-disordered breathing and its physiologic or outcome consequences.
• Translational and basic lung science: lung development, immunology, epithelial and endothelial biology, and animal/cell models that illuminate human disease.
• Clinical trials, large cohorts, and biomarker studies with respiratory or critical-illness endpoints.
• Pulmonary physiology, imaging, and -omics studies that establish a disease mechanism or a new biological insight.

Method & evidence bar

• Clinical studies must be adequately powered with prespecified, patient-centered endpoints; trials require prospective registration and the registration number.
• The applicable reporting guideline and checklist are expected: CONSORT for trials, STROBE for observational work, PRISMA for systematic reviews, ARRIVE for animal studies.
• Translational/basic work must show rigorous controls, biological replication, blinded and randomized animal experiments where applicable, and reagent/model validation.
• Mechanistic claims need direct causal evidence (perturbation, not correlation alone); human relevance should be anchored to patient samples or validated models.
• Effect estimates need confidence intervals and absolute as well as relative measures; causal language must match the design and the species/model studied.
• Sample-size, replication, and statistical-analysis plans must be explicit for both clinical and laboratory studies.

Structure & house style

• ATS format with a structured abstract and an "At a Glance Commentary" / scientific knowledge statement; re-check current article types (Original Article, Concise Clinical Study, etc.) and limits on the live guide.
• The introduction frames the biological or clinical gap; the discussion states the mechanistic insight or practice implication plainly and bounds overreach.
• A CONSORT/STROBE/PRISMA flow diagram is expected for the relevant clinical design; animal studies report ARRIVE-aligned design detail.
• Figures must show representative data with statistics, N, and replication; an online supplement carries full methods, the protocol/SAP, and additional experiments.
