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

backgroundTo identify risk factors affecting the occurrence of fetal growth restriction (FGR) in cases of thick placenta.

methodsThe retrospective study included 128 women who gave birth with a diagnosis of thick placenta between February 2016 to September 2022. Based on FGR (defined as birth weight less than the 10th percentile for gestational age), the participants were divided into FGR group and non-FGR group. Data included maternal demographic characteristics, pregnancy and placental parameters, and neonatal outcomes were analyzed.

resultsThere was no significant difference regarding maternal demographic characteristics within two groups (P > 0.05). The rate of preeclampsia and abnormal umbilical artery pulsatility index was significantly higher in FGR group compared with non-FGR group (P < 0.05); A trend of gradual growth of placental thickness and thinner thickness of initial-onset thick placenta were more frequently to see in FGR group (P < 0.05). Higher rate of worse composite neonatal outcome was noted in the FGR group as compared with non-FGR group (P < 0.05). Univariate logistic regression analysis found that the emergence of preeclampsia, abnormal umbilical artery pulsatility index, a trend of gradual growth of placental thickness and reduced thickness of initial-onset thick placenta has a positive relation with the occurrence of FGR. The highest area under curve (AUC) of thickness of initial-onset thick placenta (cutoff = 50.5 mm) for predicting FGR was 0.715. The AUC could be improved to 0,798, 0.821, 0.740 when combined with preeclampsia, abnormal umbilical artery pulsatility index, and a trend of gradual growth of placental thickness, respectively. The AUC of thickness of initial-onset thick placenta combined with preeclampsia and abnormal umbilical artery pulsatility index to predict FGR was the highest (AUC=0.869).

conclusionThickness of initial-onset thick placenta combined with preeclampsia and abnormal umbilical artery pulsatility index is expected to be valid and reliable predictors for FGR prediction.
