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
Epidemiological evidence of the blood metabolic mechanisms through which summer temperatures affect human health is scarce, despite the well-established risks and increasing severity under a warming climate. Based on the Chinese Undergraduates Cohort (CUC), we aim to explore the association between summer temperature exposure and blood metabolomics in young adults. Plasma samples were tested with an untargeted metabolomic analysis. Meteorological data was collected from China Meteorological Data Sharing Service System. The three consecutive months with the highest monthly average temperatures of the whole year were defined as summer. One-way analysis of variance (ANOVA) and the multiple linear regression model were used to assess the effects of summer mean temperature exposure on blood metabolomics, followed by stratified analysis by sex. A total of 1,930 participants, with a mean age of 18.18 ± 0.65 years, were included in this study. The summer mean temperature was 26.03 ± 1.70 °C. Metabolomic analysis identified 54 altered metabolites related to summer mean temperature, of which 7 altered metabolites were enriched in 4 significant metabolic pathways (
