Impact of autumn-winter wind speed and low temperatures on acute coronary syndrome: a 5-year single-center study in Beijing.
Article in Scientific reports, 2026. 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
Autumn-Winter weather fluctuations, especially higher wind speed and lower temperature, may trigger acute coronary syndrome (ACS). However, evidence on seasonal exposure-response curves and lag structures remains scarce. We analyzed 2445 ACS admissions from a Beijing tertiary hospital (August 2016-July 2021). Daily meteorological data were linked to admission dates. We applied season-specific analyses-including Spearman correlations, multivariable logistic regression, restricted cubic spline (RCS) curves, and lag-response models-to the autumn and winter data. Wind speed showed a linear positive association with ACS risk: autumn odds ratio (OR) 1.32 (95% confidence interval [CI]: 1.05-1.61, P < 0.05) and winter OR 1.41 (95% CI: 1.13-1.87, P < 0.05). Temperature exhibited non-linear inverse relations with thresholds at ≈ 7.5°C in autumn and - 5°C in winter; below these thresholds, the risk decreased significantly per 1 °C rise (Autumn: OR = 0.76, 95% CI: 0.25-0.96, P < 0.05; Winter: OR = 0.74, 95% CI: 0.47-0.99, P < 0.05). Lag analysis revealed the significant effects at lag 2 for wind speed (Winter OR = 1.40, 95% CI: 1.19-1.67, P < 0.05) and at lag 2 for minimum temperature (Winter OR = 0.87, 95% CI: 0.745-0.996, P < 0.05). Associations were absent in spring and summer. Elevated wind speed and extremely low temperatures are significant, lagged drivers of ACS during the cold season in Beijing. Integrating these variables into seasonal early-warning systems could improve prevention for high-risk populations.
