Hay Fever Symptom Burden From Grass Pollen: Implications for Public Health Warning Thresholds.
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
This study quantifies the lagged association between grass pollen exposure and the onset of allergic rhinitis (AR) symptoms, including differences between asthmatic and non-asthmatic subgroups. Data included 114,834 self-reported AR symptoms collected from 25,194 uniquely identified users of a smartphone application. Reports were gathered prospectively for seven consecutive grass pollen seasons (2017-2023) in Melbourne. We adjusted for meteorological, air quality, and other time-varying covariates. A quasi-Poisson regression model combined with a distributed lag non-linear model (DLNM) was used, testing 0-7 days lagged effects. An association between grass exposure and daily AR incidence of any severity was observed on "low" exposure days (19 grains/m
