Ovarian Stimulation Increases the Risk of Fetal Cardiac Defects of Pups Exposed to Severe Maternal Hyperglycemia.
Article in Gynecology & reproductive health, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectivesTo study the incidence of congenital heart defects (CHD) in offspring born to hyperglycemic mothers with and without ovarian stimulation.
designReproductive biology.
settingMouse model. PATIENTS: N/A.
interventionHyperglycemia was induced in CD-1 wild type female mice using a single intraperitoneal dose of 150 mg/kg of streptozotocin. Stimulated dams (SD); (n=3) were injected with pregnant mare serum and human chorionic gonadotropin 48 hours apart. Non-stimulated dams (NSD); (n=4) were not injected. Both groups were mated with normal male CD-1 mice for timed pregnancies. Fetal hearts were extracted on embryonic day 16.5 and histological analyses was performed. Student's t-tests were employed to compare the incidence of cardiac defects in the SD and NSD groups. P ≤ 0.05 was significant. MAIN UUTCOME MEASURE: The incidence of CHD in progeny of diabetic dams with and without ovarian hyperstimulation. RESULTS &
conclusionsThe average litter size was higher in SD compared to NSD. The average blood glucose for the SD and NSD was similar. Overall, the incidence of cardiac malformations did not differ between the two groups. However, in severe maternal hyperglycemia (>400 mg/dL), there was a higher incidence of fetal cardiac malformations in the pups born to SD vs NSD.
