Climatic Influence on COVID-19: Investigating the Role of Temperature and Humidity in the Spread of the Omicron Variant.
Article in GeoHealth, 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
Understanding how climate modulates infectious disease dynamics is critical for anticipating epidemic patterns. After a hot debate on potential facilitation of population spread by climate factors during the first 2 years of the COVID-19 pandemics, not much attention has been devoted to assess whether the ensuing SARS-CoV-2 waves also displayed similar climatic facilitation, or conversely, whether immunity dismissed any such forcing and potential signatures. This study examines the association between climatological variables-specifically temperature and absolute humidity (AH)-and the global incidence of the SARS-CoV-2 Omicron variant (B.1.1.529) during its massive epidemic wave (2021-2022). Using global-scale epidemiological and climate data, we applied the scale-dependent correlation analysis to identify transient, scale-specific non-linear associations between factors and the disease across regions. We found consistent significant local negative correlations between incidence and both temperature (
