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

objectiveTo perform three studies needed to design the "U-BET" trial (Umbilical cord Blood for Extremely-low-gestational-age Transfusions). STUDY

design(1) Survey-based self-assessment of Intermountain Health obstetricians regarding drawing umbilical cord blood. (2) Determine the percentage of the potentially donating neonates who have type O blood (to be utilized in U-BET). (3) Quantify cord blood drawn using American Red Cross collection kits.

results(1) 72% of respondents declared experience drawing cord blood; 62% with the placenta in utero. (2) Of the past 100,000 women delivering, 48% were type O, and 66% of neonates born to them were type O. (3) The volume of cord blood obtained at 10 births ranged from 20 to 86 mL after the placenta was delivered vs. 14 to157 mL when in utero.

conclusionThe U-BET trial will consent type O women and use Red Cross kits to draw term umbilical cord blood while the placenta is still in utero.
