Seasonal outdoor thermal comfort and neutral PET thresholds in a severe cold Dwa climate city of Shenyang China.
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
While outdoor thermal comfort (OTC) research in cold climate cities is expanding, comprehensive studies quantifying the seasonal impacts of urban morphology remain limited. This study fills a critical gap by establishing season-specific neutral Physiological Equivalent Temperature (PET) thresholds in Shenyang (Dwa climate, Northeast China) through 1,009 paired microclimate measurements and subjective surveys. Results show markedly lower thermal neutral points-12.5 °C in winter and 22.5 °C in summer-reflecting distinct cold-adaptive behaviors. This study provides empirical evidence quantifying the seasonal influences of urban morphology on OTC in a severe cold zone. The proposed Sky View Factor (SVF)-sensitive comfort framework advances climate-responsive design, providing empirical thresholds and parametric tools for cold-region planning. Findings contribute new evidence supporting seasonal adaptation theory and empirically offer a transferable methodology for similar high-latitude cities globally.
