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
Objectives: To clarify the relationship between maternal 50-g glucose challenge test (GCT) results and neurodevelopment in 3-year-old children and determine if low GCT results are linked to early neurodevelopmental delays in offspring. Methods: In this nationwide prospective cohort study, we extracted data from 104,062 foetal records from the Japan Environment and Children's Study. Outcomes comprised developmental status cut-off values for the domains of the Ages and Stages Questionnaire, Third Edition. The exclusion criteria were gestational diabetes mellitus, diabetes during pregnancy, and GCT results ≥ 140 mg/dL. Based on these criteria, we included 12,472 women who had undergone a GCT between 14 and 27 weeks of gestation and divided the participants into a low-GCT group (cohort specific ≤ 10th percentile, ≤ 81 mg/dL) and a non-low-GCT group (82-139 mg/dL). Multivariable logistic regression analysis was used to investigate the association between low GCT results and early neurodevelopmental delays. Results: Compared with infants born to women with normal GCT results, those born to women with low GCT results showed a significantly higher incidence of neurodevelopmental delays, particularly in communication, gross motor, fine motor, and problem-solving skills (adjusted odds ratio [OR] 1.35, 95% confidence interval [CI] 1.02-1.78; adjusted OR 1.31, 95% CI 1.01-1.69; adjusted OR 1.26, 95% CI 1.02-1.56; adjusted OR 1.24, 95% CI 1.01-1.54, respectively). No significant increase in the adjusted ORs (95% CIs) was observed for female offspring. Conclusions: Low maternal GCT results are associated with offspring neurodevelopment at 3 years of age, with the association influenced by offspring sex.
