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

Fetomaternal hemorrhage refers to a clinical syndrome in which fetal blood enters the maternal circulation through the placental villous spaces, typically triggered by specific stimuli, and may lead to fetal anemia or maternal hemolysis. The occurrence of fetomaternal hemorrhage is very rare in singleton pregnancies and even rarer in multiple gestations. In monochorionic diamniotic twin pregnancies, shared placental circulation can amplify the consequences of fetomaternal hemorrhage, potentially resulting in more severe outcomes than in singleton pregnancies or in twins with double chorions and double amniotic sacs. A 39-year-old woman, natural conception, gravida 3, para 1, monochorionic diamniotic twins, refused to terminate the pregnancy at 36 + 3 days. An emergency cesarean delivery was performed at 37 + 3 weeks because of a sinusoidal fetal heart rate pattern, with a decision-to-delivery interval of 27 min. Both neonates were born with severe neonatal asphyxia and anemia but demonstrated favorable recovery with resuscitation of neonatal asphyxia and transfusion therapy. Flow cytometric analysis of maternal blood revealed a fetal hemoglobin F fraction of 11.93%, confirming fetomaternal hemorrhage.
