Effect and safety of timing of cord clamping on neonatal hematocrit values and clinical outcomes in term infants: A randomized controlled trial.
Trial report in Journal of perinatology : official journal of the California Perinatal Association, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 17 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveTo evaluate the effect and safety of different umbilical cord clamping (UCC) timing. STUDY
designThis was a randomized trial of 720 term mothers/infants from the Tianjin Central Hospital of Obstetrics and Gynecology delivered from December 2014 to May 2015 and randomized to immediate cord clamping (ICC) within 15 s, delayed cord clamping (DCC) by 30, 60, 90, 120, 150, or 180 s, or when the umbilical cord pulsation ceased.
results24 h after delivery, the mean infant hematocrit levels were 56.5, 57.3, 58.8, 59.7, 59.5, 59.7, 60.3, and 61.0% in the ICC, 30, 60, 90, 120, 150, and 180-second DCC, and no pulsation groups, respectively (P = 0.021, 0.001, 0.003, 0.001, <0.001, and <0.001, respectively; standard deviations ranging 5.4-8.7%). There was no significant difference between the 30-second DCC and ICC groups. No significant differences were found in other neonatal and maternal outcomes among these groups.
conclusionFor term infants, DCC increases the hematocrit values, without apparent harmful effects on the infants and their mothers.
