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

backgroundGestational weight gain (GWG) plays a critical role in determining birth outcomes, especially in twin pregnancies. However, the association between GWG and adverse birth outcomes in twin pregnancies remains inconclusive. This study aims to define GWG according to different classification criteria and explore their associations with adverse birth outcomes in twin pregnancies.

methodsThis was a prospective cohort study that included 1,029 twin pregnant women recruited from Qingdao Women and Children's Hospital between September 2018 and December 2020. Participants were categorized into insufficient, adequate, and excessive GWG groups using both the interquartile range (P25-P75) method and the Institute of Medicine (IOM) criteria. Logistic regression models were employed to assess the associations between GWG and adverse birth outcomes, including preterm birth (PTB), low birth weight (LBW), and small for gestational age (SGA).

resultsAccording to the interquartile range method, women in the insufficient GWG group had a significantly increased risk of PTB (OR: 2.13, 95% CI: 1.55-2.94), LBW (OR: 2.01, 95% CI: 1.33-3.05), and SGA (OR: 1.62, 95% CI: 1.03-2.54) compared to adequate GWG group. In contrast, the excessive GWG group was associated with a reduced risk of LBW (OR: 0.64, 95% CI: 0.45-0.92) and SGA (OR: 0.51, 95% CI: 0.28-0.91) after adjusting for potential confounders. Similar trends were observed using the IOM criteria, with a significantly increased risk of PTB and LBW in twin pregnant women with insufficient GWG and a reduced risk of SGA with excessive GWG.

conclusionsAchieving an appropriate level of weight gain during pregnancy is essential to reduce the risk of adverse birth outcomes in women with twin pregnancies.
