Gestational weight gain during pregnancy is the risk factor for Omicron infection: a retrospective case-control study.
Article in BMC pregnancy and childbirth, 2024. 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
backgroundIt remains unclear whether gestational weight gain (GWG) during pregnancy is associated with Omicron infection in pregnant women.
objectiveTo investigate whether gestational weight gain during pregnancy is associated with an increased risk of Omicron infection.
methodsThis is a retrospective case-control study of pregnant women from The Third Affiliated Hospital of Sun Yat-sen University from December 1 to 31, 2022. Pregnant women infected with Omicron were compared to those uninfected using chi-square statistics for categorical variables and t-tests or ANOVA for continuous variables. Multivariable logistic regression, along with subgroup analyses, was used to investigate the association between gestational weight gain during pregnancy and Omicron infection.
resultsOur study included 369 pregnant women who met the eligibility criteria. The proportion of pregnant women in the term, infected and uninfected with Omicron was 113(30.6%) and 256(69.4%). Classified pregnant women according to GWG during pregnancy, GWG during pregnancy above IOM was significantly associated with an increased risk of Omicron infection (P = 0.006). After adjusting for demographic factors and pregnancy complications, this association was particularly notable (OR = 2.55, 95%CI = 1.35-4.85, P = 0.004). Classified pregnant women according to pregestational BMI, in normal-weight pregnant women, GWG during pregnancy above IOM was significantly associated with an increased risk of Omicron infection (P = 0.01). After adjusting for demographic factors and pregnancy complications, this association was particularly notable (OR = 2.56, 95%CI = 1.24-5.31, P = 0.01).
conclusionAmong women with normal weight, gestational weight gain during pregnancy above IOM was an independent risk factor for Omicron infection.
