Which factor reflects applicability of a randomized trial to a patient?

Assessing applicability to a patient focuses on external validity—the extent to which trial findings generalize to real patients like the one you’re treating. The most important factor is whether the patient’s characteristics match the trial participants (age, disease type and severity, comorbidities, prior treatments) and whether the interventions and outcomes studied are relevant to the patient’s situation. When these fit, the trial’s results are more likely to be useful for guiding care. Journal quality, how old the study is, and how many authors worked on it don’t determine whether the findings apply to a specific patient. They relate to publication quality, currency, and authorship, not to patient-level applicability.
