Effect of Delayed Cord Clamping at 30 Seconds and 1 Minute on Neonatal Hematocrit in Term Cesarean Delivery: A Randomized Trial.
Article in International journal of women's health, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04812223 (Prospective Randomized Comparison of the Results of Early Clamping, Delayed Clamping and Milking of the Umbilical Cord in Term Cesarean Deliveries), which is not on this map. Cited by 5 papers, 2 of them syntheses that pooled 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.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Abstract
objectiveTo compare the effect of delayed cord clamping at 30 seconds and 1 minute on the incidence of neonatal hematocrit, anemia, maternal and neonatal complications in term cesarean delivered neonates.
methodsAn opened labelled, randomized controlled trial was undertaken. The 160 healthy term cesarean-born neonates were randomly allocated to either 30 seconds or 1-minute groups of delayed cord clamping (DCC) (groups 1 and 2). Neonatal venous hematocrit (Hct) and microbilirubin (Mb) were measured at 48-72 hours after birth.
resultsOne hundred and fifty-nine neonates completed this study. Mean neonatal hematocrit ± standard deviation at 48-72 hours was 49.9 ± 6.0% in group 1 and 51.2 ± 5.9% in group 2 without a statistical difference. Neonatal anemia (Hct less than 45%) occurred in 14/79 neonates (17.7%) in group 1 and in 8/80 cases (10.0%) in group 2 without a significant difference between groups. The incidence of neonatal jaundice and polycythemia (hematocrit more than 65%) was similar between groups. There were no significant differences; in the estimated blood loss during the operation, the incidence of postpartum hemorrhage and other maternal and neonatal complications.
conclusionNeonatal hematocrit was not significantly different following DCC at 30 seconds and at 1 minute, but the incidence of neonatal anemia decreased with the longer timing of DCC. The estimated blood loss and other complications were not different between the two groups. Therefore, one minute-DCC should be considered for neonatal anemic prevention when compared with 30 seconds-DCC.
