Identifying the correlation between the number of OGTT abnormalities and perinatal outcomes in twin pregnancies: a retrospective cohort study.

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
Introduction: Gestational diabetes mellitus (GDM) is a common metabolic disorder during pregnancy and is particularly significant in twin pregnancies due to their inherently higher risk of adverse perinatal outcomes. Identifying the correlation between the degree of glucose intolerance and perinatal outcomes can provide valuable insights for clinical management. This study aimed to investigate the risk of developing adverse perinatal outcomes in pregnant women and fetuses with twin births by the number of abnormal values of oral 75 g glucose tolerance test (OGTT). Methods: We conducted a population-based retrospective cohort study in which 3545 pregnant women with twin pregnancies in Women's and Children's Hospital of Chongqing Medical University underwent an oral 75 g glucose tolerance test to collect fasting, 1-hour postprandial, and 2-hour postprandial glucose, and to collect the perinatal outcomes of pregnant women and fetuses in the set. Results: Logistic regression analysis showed that the number of abnormal OGTTs was associated with the risk of expected adverse perinatal outcomes. In the unadjusted model, the prevalence of gestational hypertension, intrahepatic cholestasis in pregnancy, and hypoproteinemia in pregnancy were statistically significant. In the adjusted model, the prevalence of gestational hypertension and intrahepatic cholestasis in pregnancy was statistically significant. Conclusions: The number of abnormal OGTTs was associated with the incidence of gestational hypertension and intrahepatic cholestasis in pregnancy in twin pregnancies that had undergone assisted reproduction. These findings highlight the importance of closely monitoring glucose levels in such pregnancies to mitigate associated risks.
