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

objectiveThe objective was to study the relationship between a decrease in gross fetal movement during maternal night sleep counted by an objective method and abnormal perinatal outcomes.

methodsThis was a prospective cohort study. A total of 470 pregnant women recorded fetal movement with the fetal movement acceleration measurement recorder weekly after 28 weeks. The ratio of 10-s epochs with fetal movement to all epochs was calculated as the fetal movement parameter. When the parameter was below the 10th percentile of the previously made reference curve, it was defined as decreased movement. Women who showed a decreased movement at least once were classified into a study group, and the other women were classified into a control group. Abnormal perinatal outcomes between the two groups were compared with the Chi-square test.

resultsThere were more preterm births (19%) in the study group than in the control group (10%) (P = 0.0210). There was a significant difference for iatrogenic preterm birth (P = 0.0241) but not for spontaneous preterm birth (P = 0.4566). There were more hypertensive disorders of pregnancy (11.6%), small-for-gestational-age newborns (10.7%), and Apgar scores below 7 points at 1 min (7.4%) in the study group than in the control group (5.2%, 4.8%, and 2.6%, respectively) (P = 0.0329, 0.0459, and 0.0487, respectively).

conclusionA decrease in gross fetal movement during maternal night sleep was related to iatrogenic preterm births, small-for-gestational-age newborns, hypertensive disorders of pregnancy, and low Apgar scores at 1 min.
