Evaluating the Impact of Gestational Weight Gain Based on an Increase in BMI Class in Patients with Obesity During Pregnancy.
Article in Maternal and child health journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
objectiveTo evaluate the impact of BMI class increase during pregnancy on perinatal outcomes.
methodsThis retrospective cohort study from 2009 to 2022 included singleton pregnancies with a pre-gravid BMI ≥ 30 kg/m
results16,835 pregnancies were included. The majority of patients were White/not Hispanic (80.3%) and multiparous (65.6%); co-morbidities increased as BMI increased. An increase from BMI class I to II led to more adverse outcomes than maintaining class I BMI (aOR 1.17, 95% CI 1.06, 1.28), and equivalent outcomes as those who had a pre-gravid class II BMI (adjusted 90% CI, -0.022, 0.019; p < 0.01). This increased odds of adverse outcomes doubled when the BMI increase from I to II occurred prior to 30 weeks gestation (aOR 1.34, 95% CI 1.21, 1.48). An increase from BMI class II to III led to higher odds of adverse outcomes than maintaining BMI class II (aOR 1.40, 95% CI 1.25, 1.58). The data does not provide sufficient evidence that the outcomes were equivalent to those with a pre-gravid BMI class III (adjusted 90% CI, -0.52, -0.017; p = 0.26). CONCLUSIONS FOR PRACTICE: For pregnant patients with obesity, recommendations for pregnancy management should be based on current BMI, rather than pre-gravid BMI.
