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
Objective: The study aimed to obtain more evidence on the association of gestational weight gain and pre-pregnancy body mass index (BMI) with macrosomia. Methods: The data on 5409 live births delivered at Peking Union Medical College Hospital from July 2020 to June 2022 were collected. Group analyses were performed according to the presence or absence of macrosomia. Multivariable binary logistic regression and incidence heatmaps was used to analyze the related factors of macrosomia. Results: The following variables were significantly associated with macrosomia: overweight (odds ratio [OR]: 2.24, 95% confidence interval [CI]: 1.62-3.10), obesity (OR: 4.56, 95% CI: 2.93-6.98), excessive gestational weight gain (OR: 2.39, 95% CI: 1.67-3.43), gestational age at delivery at 39-41 weeks (OR: 3.83, 95% CI: 2.56-5.95), gestational age at delivery over 41 weeks (OR: 7.88, 95% CI: 4.37-14.19), education level of junior college or below (OR: 1.95, 95% CI: 1.19-3.09), and multipara (OR: 1.62, 95% CI: 1.09-2.42). "v" represents the mean weekly weight gain during the second and third trimesters. A higher v value increased the risk of macrosomia by 2.6-fold (95% CI: 1.37-4.89, P = 0.003). Compared to normal weight women, after adjustment for different pre-pregnancy BMI subgroups, overweight pregnant women had higher weekly weight gain in the second and third trimesters (OR: 4.57, 95% CI: 2.27-9.10, P < 0.001). Obese pregnant women had higher average weekly weight gain during the second and third trimesters, and the OR value for macrosomia was 11.33 (95% CI: 4.95-25.18, P < 0.001). To reduce the incidence of macrosomia in overweight pregnant women, v = 0.32 could be considered the critical threshold of average weekly weight gain in these women in the second and third trimesters of pregnancy. Conclusion: Pre-pregnancy BMI and weight gain during pregnancy are closely related to macrosomia. The introduction of average weekly weight gain values in the second and third trimesters of pregnancy probably help pregnant women minimizing adverse pregnancy-related outcomes.
