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

backgroundThe cesarean section rate (CSR) has been a main concern worldwide. The present study aimed to investigate the CSR in Beijing, China, and to analyze the related factors of CS delivery.

methodsAn observational study was conducted in 15 medical centers in Beijing using a systemic cluster sampling method. In total, 15,194 pregnancies were enrolled in the study between June 20, 2013 and November 30, 2013. Independent t-tests and Pearson's Chi-square test were used to examine differences between two groups, and related factors of the CSR were examined by multivariable logistic regression.

resultsThe CSR was 41.9% (4471/10,671) in singleton primiparae. Women who were more than 35 years old had a 7.4-fold increased risk of CS delivery compared with women <25 years old (odd ratio [OR] = 7.388, 95% confidence interval [CI] = 5.561-9.816, P < 0.001). Prepregnancy obese women had a 2-fold increased risk of CS delivery compared with prepregnancy normal weight women (OR = 2.058, 95% CI = 1.640-2.584, P < 0.001). The excessive weight gain group had a 1.4-fold increased risk of CS delivery compared with the adequate weight gain group (OR = 1.422, 95% CI = 1.289-1.568, P < 0.001). Gestational diabetes mellitus (GDM) women and DM women had an increased risk of CS delivery (1.2- and 1.7-fold, respectively) compared with normal blood glucose women. Women who were born in rural areas had a lower risk of CS delivery than did those who were born in urban areas (OR = 0.696, 95% CI = 0.625-0.775, P < 0.001). The risk of CS delivery gradually increased with a decreasing education level. Neonates weighing 3000-3499 g had the lowest CSR (36.2%). Neonates weighing <2500 g had a 2-fold increased risk of CS delivery compared with neonates weighing 3000-3499 g (OR = 2.020, 95% CI = 1.537-2.656, P < 0.001). Neonates weighing ≥4500 g had an 8.3-fold increased risk of CS delivery compared with neonates weighing 3000-3499 g (OR = 8.313, 95% CI = 4.436-15.579, P < 0.001).

conclusionsMaternal age, prepregnancy body mass index, gestational weight gain, blood glucose levels, residence, education level, and singleton fetal birth weight are all factors that might significantly affect the CSR.
