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 compare risks of pregnancy and birth in obese (body mass index, BMI ≥ 30) and normal weight women (BMI 18.5-24.99) giving birth to their first child.

methodsWe analysed data of 243,571 pregnancies in primiparous women from the German perinatal statistics of 1998-2000. We calculated odds ratios (ORs) with 95% confidence intervals (CIs) for selected pregnancy and birth risks. ORs were adjusted for the confounding factors age, smoking status, single mother status, and maternal education.

resultsObesity during pregnancy is common in primiparous women (n = 19,130; 7.9% of all cases) and it is significantly associated with a number of risks of pregnancy and birth, including diabetes [OR 3.71 (95% CI 2.93; 4.71); p < 0.001], hypertension [OR 8.44 (7.91; 9.00); p < 0.001], preecalmpsia/eclampsia [OR 6.72 (6.30; 7.17); p < 0.001], intraamniotic infection [OR 2.33 (2.05; 2.64); p < 0.001], birth weight ≥ 4,000 g [OR 2.16 (2.05; 2.28); p < 0.001], and an increased rate of Caesarean section [OR 2.23 (2.15; 2.30); p < 0.001]. Some risks were less frequent in the obese such as cervical incompetence [OR 0.55 (0.48; 0.63); p < 0.001] and preterm labour [OR 0.47 (0.43; 0.51); p < 0.001].

conclusionsObesity during pregnancy is an important clinical problem in primiparous women because it is common and it is associated with a number of risks of pregnancy and birth. Because of these increased risks, obese women need special attention clinically during the course of their first pregnancy. Weight reduction before the first pregnancy is generally indicated in obese women to prevent the above-mentioned complications of pregnancy and birth.
