Fig. 3From: Porcine versus bovine surfactant therapy for RDS in preterm neonates: pragmatic meta-analysis and review of physiopathological plausibility of the effects on extra-pulmonary outcomesComparisons poractant-α vs bovine surfactants for PDA. The panel (1472 patients) illustrates meta-analyses of any dose of poractant-α vs bovine surfactants with random-effects model. Poractant-α and bovine surfactants are considered as treatment (Trt) and control (Ctrl) arm, respectively; events (Ev) per arm and odds ratio (95%CI) are reported. Squares and horizontal lines represent odds ratios and their 95%CI, respectively. The location of the diamond and its width represent the pooled estimated effect size and its 95%CI, respectivelyBack to article page
