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.

2 · The registry

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

backgroundIn 2015, the American Academy of Pediatrics recommended delayed umbilical cord clamping for at least 30-60 s for all infants. However, there is limited data regarding the maternal safety of delayed cord clamping in multiple pregnancies. We aimed to compare the maternal bleeding complications following early cord clamping (ECC) versus of delayed cord clamping (DCC) in multiple pregnancies.

methodsA retrospective cohort study of pregnant women with multiples who delivered live-born infants at Sharp Healthcare Hospitals in San Diego, CA, USA during January 1st, 2016 - September 30th, 2017. Bleeding complications of 295 women who underwent ECC (less than 30 s) were compared with 154 women who underwent DCC (more than 30 s). ECC or DCC was performed according to individual obstetrician discretion.

resultsFour hundred forty-nine women with multiple pregnancies (N = 910 infants) were included in the study. 252 (85.4%) women underwent cesarean section in ECC group vs. 99 (64.3%) in DCC group. 58 (19.7%) women delivered monochorionic twins in ECC group vs. 32 (20.8%) women in DCC group. There was no increase in maternal estimate blood loss when DCC was performed comparing to ECC. There were no differences in operative time, post-delivery decrease in hematocrits, rates of postpartum hemorrhage, bleeding complications, maternal blood transfusions and therapeutic hysterectomy between the two groups.

conclusionsNo differences in maternal bleeding complications were found with DCC in multiple pregnancies compared to ECC. Delayed cord clamping can be done safely in multiple pregnancies without any increased maternal risk.
