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

introductionThe aim of this study was to describe maternal and perinatal outcomes in pregnant women with sickle cell disease (SCD) followed at Santa Casa de Sao Paulo over a 10-year period (between 2010 and 2019).

methodFifty-five records of pregnancies were analyzed among 35 women with SCD.

resultsAmong 29 newborns, 19 (65.5%) were full-term and 10 pre-term; 24 (82.7%) caesareans and 5 (17.2%) natural births were observed. The mean gestational age at birth and mother`s age were 36.6 weeks (30-40) and 26.7 years (17-39), respectively. No maternal death was observed. The main maternal obstetric and non-obstetric complications were: pre-eclampsia and gestational diabetes, and vaso-occlusive crisis, urinary tract infection and acute chest syndrome, respectively. Twenty-six (47.0%) fetal deaths were observed, 24 being intrauterine fetal (14 early abortions, 10 late abortions and 2 stillbirths). Regarding the red blood cell transfusion history, 40 (72.7%) out of 55 pregnancies received transfusion. Pregnant women who received 6 or more transfusions throughout pregnancy had a significantly lower number of abortions, i.e., no cases of early abortion and only 1 case of late abortion, versus 14 and 9 cases in pregnancies with 0-5 transfusions, respectively. Despite advances in the management of SCD, pregnant women with SCD (particularly those with HbSS) are at a high risk for maternal and fetal complications, even though they are followed in reference centers.

conclusionThe lower risk of intrauterine fetal death for those women who received more transfusions throughout pregnancy observed in the current study leads us once more to raise the need for prospective, multicenter, randomized trials to determine whether the potential benefits balance the risks of prophylactic transfusions.
