PRISMA diagram of the literature‐screening process for the NSCLC SLR and meta‐analysis. ^aLC types were SCLC (n = 2) or malignant pleural mesothelioma (n = 1). ^bOutcomes were PFS or weight gain. ^cWL analysed as quartiles or as a continuous variable in MVA. ^dWL assessment periods were during treatment rather than at baseline. HR, hazard ratio; IC, international consensus; KM, Kaplan–Meier; LC, lung cancer; MVA, multivariate analysis; NSCLC, non‐small‐cell lung cancer; PFS, progression‐free survival; PRISMA, Preferred Reporting Items for Systematic Reviews and Meta‐Analyses; SCLC, small‐cell lung cancer; SLR, systematic literature review; WL, weight loss.
