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

purposeTo examine the impact of young maternal age on miscarriages and stillbirths in rural Southern Nepal.

methodPregnancies, miscarriages, and stillbirths were prospectively identified in two randomized trials of maternal micronutrient supplementation. This analysis included 5861 women of parity 0 (nulliparas) and 4459 of parity 1 (primiparas) who were <26 years of age.

resultsAmong nulliparous women, 5.7% and 4.6% of pregnancies ended in miscarriage and stillbirth. The adjusted relative risk of miscarriage was 2.07 for girls <15 (95% confidence interval [CI] = 1.17-3.66) compared with those 18 and 19 years, and was 1.40 (95% CI = 1.06-1.84) among those 15-17 years. Stillbirth rates did not differ significantly by maternal age. There were no differences in miscarriage or stillbirth rates by maternal age among primiparas.

conclusionYoung maternal age increased the risk of miscarriages but not stillbirths for nulliparas. Miscarriages and stillbirths did not differ by maternal age for primiparous women.
