The sequelae of the COVID-19 pandemic on maternal body mass index, gestational weight gain, and delivery-associated birth complications: a nationwide epidemiologic study.
Article in BMC public health, 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
backgroundEvidence as to whether COVID-19-mitigating measures affected the metabolic status of pregnant women is lacking. This is the first study to analyze changes in pre-pregnancy weight, body mass index (BMI), gestational weight gain (GWG), the prevalence of overweight and obese women conceiving, and delivery-associated complications during the COVID-19 pandemic compared to pre-pandemic times.
methodsThis nationwide cohort study analyzed birth registry data from all obstetric departments in Austria. The period from 05 to 12/2020 was defined as the pandemic period (N = 30,806), whereas the period from 05-12/2015-2019 was defined as the pre-pandemic period (N = 162,463).
resultsThe pre-pregnancy weight and BMI were 64 (57-73) kg and 23.03 (20.70-26.37) kg/m
conclusionsCOVID-19-mitigating measures worsened the metabolic status of pregnant women. To counteract this, targeted intervention programs must be implemented immediately as an integral part of the pandemic recovery plan.
