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
introductionThe global obesity epidemic presents a growing challenge in perinatal medicine and obstetrics, as it is associated with a higher risk of adverse maternal and perinatal outcomes. In addition to metabolic disturbances, obesity contributes to chronic low-grade inflammation. This study aims to investigate the relationship between maternal overweight, obesity, and excessive weight gain during pregnancy and high-sensitivity C-reactive protein (hs-CRP), an acute-phase reactant of inflammation and infection in maternal serum. MATERIAL AND
methodsThe PRINCE (Prenatal Identification of Children's Health) study is a prospective longitudinal pregnancy cohort conducted at the University Medical Centre Hamburg-Eppendorf in Germany. In this study, biosamples and metadata were collected from 2011 to 2023. Hs-CRP levels were measured in each trimester among 582 healthy, low-risk women. Participants were categorized into weight classes based on their body mass index. Weight gain during pregnancy was evaluated according to the recommendations of the Institute of Medicine. For statistical analysis, the Wilcoxon and Kruskal-Wallis tests were employed for continuous variables, whereas the Mann-Whitney test was used for binary groups.
resultsHs-CRP levels are significantly higher in overweight and obese pregnant women throughout their pregnancy. During the first trimester, hs-CRP compared to those of normal-weight individuals (mean 3.4 mg/L; 95% CI 3.1 to 3.7) showed a 1.7-fold increase in overweight (mean 5.9 mg/L; 95% CI 5.0 to 6.7; p < 0.0001) and a 2.7-fold increase in obesity (mean 9.3 mg/L; 95% CI 7.6 to 11.0; p < 0.0001). Excessive weight gain during pregnancy is more common among overweight women (67%) and is associated with 1.5-fold heightened hs-CRP levels in the third trimester (mean 5.6 mg/L; 95% CI 4.7 to 6.4), compared to overweight women who follow the recommended weight gain guidelines (mean 3.7 mg/L; 95% CI 2.9 to 4.4; p = 0.009).
conclusionsOverweight and obesity, along with excessive gestational weight gain in individuals with preexisting overweight status, correlate with elevated levels of hs-CRP during pregnancy. This phenomenon indicates chronic low-grade inflammation in adipose tissue.
