Interactive effects of diurnal temperature range and air pollution on myocardial infarction incidence: an individual-level case-crossover study.
Article in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Climate change and air pollution have garnered increasing attention in recent years due to their potential to contribute to various diseases, including myocardial infarction (MI). However, no previous studies have explored the interactive effects of diurnal temperature range (DTR) and air pollution on MI. This study employed an individual-level time-stratified case-crossover design to investigate 391,901 MI patients in central China between 2017 and 2020. Daily estimated air pollutant concentrations for each patient were extracted from gridded datasets based on their residential addresses on both case and control days. Conditional logistic regression models were used to examine the lagged effects and exposure-response relationships between short-term exposure to air pollutants, DTR, and MI. Additionally, the relative excess odds due to interaction (REOI), proportion attributable to interaction, and synergy index were applied to quantify the interaction effects. Subgroup analyses were further conducted by gender and age (≥ 65 years old and < 65 years old) to identify vulnerable populations. Exposure to all six air pollutants (PM2.5, PM10, SO
