1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract

objectiveTo assess the effect of delayed cord clamping (DCC) vs immediate cord clamping (ICC) on intraventricular hemorrhage (IVH), late onset sepsis (LOS), and 18-month motor outcomes in preterm infants. STUDY

designWomen (n = 208) in labor with singleton fetuses (<32 weeks gestation) were randomized to either DCC (30-45 seconds) or ICC (<10 seconds). The primary outcomes were IVH, LOS, and motor outcomes at 18-22 months corrected age. Intention-to-treat was used for primary analyses.

resultsCord clamping time was 32 ± 16 (DCC) vs 6.6 ± 6 (ICC) seconds. Infants in the DCC and ICC groups weighed 1203 ± 352 and 1136 ± 350 g and mean gestational age was 28.3 ± 2 and 28.4 ± 2 weeks, respectively. There were no differences in rates of IVH or LOS between groups. At 18-22 months, DCC was protective against motor scores below 85 on the Bayley Scales of Infant Development, Third Edition (OR 0.32, 95% CI 0.10-0.90, P = .03). There were more women with preeclampsia in the ICC group (37% vs 22%, P = .02) and more women in the DCC group with premature rupture of membranes/preterm labor (54% vs 75%, P = .002). Preeclampsia halved the risk of IVH (OR 0.50, 95% CI 0.2-1.0) and premature rupture of membranes/preterm labor doubled the risk of IVH (OR 2.0, 95% CI 1.2-4.3).

conclusionsAlthough DCC did not alter the incidence of IVH or LOS in preterm infants, it improved motor function at 18-22 months corrected age. CLINICAL
