Impact of fertility treatments on perinatal outcomes in pregnancies complicated by GDMA1: a comparative 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
objectiveTo investigate adverse pregnancy and delivery outcomes in women with GDMA1 during pregnancies conceived through fertility treatments.
methodsThis population-based retrospective cohort study examined adverse pregnancy and delivery outcomes in pregnancies affected by GDMA1 following fertility treatments compared to those conceived naturally. Women with GDMA1 who conceived via fertility treatments were classified as cases, while those who conceived naturally were designated as controls. Multivariable logistic regression models were employed to evaluate the association between fertility treatments and perinatal outcomes in pregnancies complicated by GDMA1.
resultsThe study cohort consisted of 12,841 pregnant women diagnosed with GDMA1, of whom 640 (4.98%) conceived through fertility treatments, while the remaining 12,201 conceived naturally. Women with GDMA1 who conceived through fertility treatments had significantly higher rates of preeclampsia, hypertension, preterm birth, and cesarean delivery, while they experienced lower rates of macrosomia and polyhydramnios compared with women who conceived spontaneously. Multivariate analysis identified fertility treatments as an independent predictor of cesarean delivery, while conversely serving as a protective factor against macrosomia after adjusting for maternal age, parity, hypertensive disorders of pregnancy, and labor induction.
conclusionWomen with GDMA1 who conceived through fertility treatments experienced a reduced incidence of complications associated with GDM, such as macrosomia and polyhydramnios. This could be explained by better GDM control and adherence to a more rigorous prenatal care approach. However, they faced an increased risk of other obstetric complications, including pre-eclampsia, preterm delivery, and cesarean delivery.
