Early Pregnancy in Times of Climate Change: First-Trimester Heat Exposure Is Associated With Reduction in Fetal Crown-Rump Length in the 12th/13th Week of Gestation-A Retrospective Study From Vienna, Austria.
Article in American journal of human biology : the official journal of the Human Biology Council, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectivesThis study focused on the association between fetal crown-rump length (CRL) in the 12th/13th gestational week and the number of 1st trimester heat days to assess the impact of rising temperature on intrauterine growth in early pregnancy.
methodsThis single-center medical record-based study comprises 10 085 singleton live births (n
resultsCRL decreased significantly (p < 0.001) by 0,015 mm on average per heat day in the 1st trimester. Among male fetuses, CRL decreased significantly (p < 0.001) by 0,021 mm, while among female fetuses, only an insignificant decrease was observed.
conclusionHeat days during the 1st trimester could have a small adverse effect on early fetal growth.
