In Underweight Women, Insufficient Gestational Weight Gain Is Associated with Adverse Obstetric Outcomes.
Observational study in Nutrients, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 19 papers.
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
The pre-pregnancy BMI and the gestational weight gain are two important determinants of pregnancy outcomes. The aim of this study was to determine obstetric outcomes associated with insufficient gestational weight gain in women with a pre-pregnancy BMI < 18.5 kg/m2. This study was based on observational routinely collected data from University Hospital Maternity. The participants were allocated to the group sufficient or insufficient gestational weight gain: ≥12.5 kg and <12.5 kg respectively. Primary outcomes were the adjusted birth weight in percentiles (%) and the proportion of SGA newborns. Secondary outcomes were obstetric and perinatal outcomes. A total of 132 participants with a median age of 28 ± 8 years were included. The adjusted birth weight in percentiles was significantly lower in the insufficient gestational weight gain group (27.3 ± 45.0 vs. 46.3 ± 46.2%; p < 0.001). Moreover, the insufficient gestational weight gain is associated with a higher risk of SGA (27.0% vs. 11.6%; p = 0.03). Our study also showed increased risks of premature rupture of membranes, anaemia, and intrauterine growth restriction in women with an insufficient weight gain. Future studies should explore the risk factors associated with insufficient weight gain, in order to develop specific care for underweight pregnant women.
