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 evaluate stillbirth trends by gestational age.

methodsNational Center for Health Statistics' fetal death and live birth data files were used to analyze the 2006 and 2012 cohorts of deliveries and compute gestational age-specific stillbirth rates at 20 weeks of gestation or greater using two methods: traditional (eg, stillbirths at 38 weeks of gestation/live births and stillbirths at 38 weeks of gestation) and prospective (stillbirths at 38 weeks of gestation/number of women still pregnant at 38 weeks of gestation). Changes in rates and in the percent distribution of stillbirths and live births were assessed.

resultsIn 2006 and 2012, the stillbirth rate was 6.05 stillbirths per 1,000 deliveries. There was little change in the percent distribution of stillbirths by gestational age from 2006 to 2012. However, the percent distribution of live births by gestational age changed considerably: births at 34-38 weeks of gestation decreased by 10-16%, and births at 39 weeks of gestation increased by 17%. Traditionally computed stillbirth rates were unchanged at most gestational ages, but rose at 24-27, 34-36, 37, and 38 weeks of gestation. However, rates were influenced by decreases in births at those gestational ages; the pattern of stillbirths by gestational age was unchanged. In contrast, there were no differences in prospective stillbirth rates at 21-42 weeks of gestation.

conclusionThe lack of change in prospective stillbirth rates from 2006 to 2012 suggests that preventing nonmedically indicated deliveries before 39 weeks of gestation did not increase the U.S. stillbirth rate. LEVEL OF EVIDENCE: II.
