Comparisons poractant-α vs bovine surfactants for BPD (a-b) and surfactant redosing (c-d). Panels a (1193 patients) and c (1164 patients) illustrate meta-analyses of 200 mg/kg poractant-α vs bovine surfactants; panels b (1370 patients) and d (1372 patients) illustrate meta-analyses of any dose of poractant-α vs bovine surfactants. Poractant-α and bovine surfactants are considered as treatment (Trt) and control (Ctrl) arm, respectively; events per arm and odds ratio (95%CI) are reported. All analyses have been performed with random effect model
