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

Objective: To analyze the adequacy of gestational weight gain (GWG) and associated factors, according to the Brazilian GWG charts, and compare with the Institute of Medicine (IOM) recommendations. Methods: This was a cross-sectional study. Sociodemographic, clinical, and obstetric data were collected from interviews and medical records. The sample was divided into three groups according to the Brazilian charts: insufficient GWG, adequate GWG, and excessive GWG. The chi-square and Kruskal-Wallis tests were used to compare frequencies and medians, respectively, and Dunn's test was used to verify differences between groups, assuming statistical significance of p<0.05. Results: Seven hundred and twenty-five women with low-and high-risk pregnancies were evaluated. Using the Brazilian charts, the prevalence of insufficient, adequate, and excessive GWG was 25.8%, 21.1%, and 53.1%, respectively. Compared with the classifications given using the IOM method, there was a lower prevalence of insufficient and adequate GWG and a higher prevalence of excessive GWG. The sensitivity and specificity of the Brazilian charts versus the IOM recommendations were 100% and 76.6%, respectively, for excessive GWG and 72.3% and 20%, respectively, for insufficient GWG. The modifiable factors related to GWG were pregestational BMI (p=0.001) and number of consultations with a nutritionist (p=0.008). Conclusion: Studies evaluating the Brazilian GWG charts are scarce. The Brazilian charts indicated a higher prevalence of excessive GWG than the IOM recommendations. The sensitivity and specificity of the Brazilian charts were better for excessive GWG than for insufficient GWG, using the IOM recommendations as the standard.
