1 · What the graph read from it

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.

2 · The registry

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

backgroundPrior studies have shown that climate factors and air pollution are associated with hand, foot, and mouth disease (HFMD) epidemics. However, the interaction between air pollution and climate factors remains unknown.

methodsDaily HFMD counts from 2009 through 2012 in Guangdong were collected. We used distributed lag non-linear models to assess the associations of climate factors and air pollution on HFMD cases. The effects of climate factors were stratified by air pollution stratum to examine the interaction effect of air quality index (AQI) and temperature, as well as relative humidity. In addition, we explored the variability across gender groups.

resultsWe observed associations between HFMD cases and environmental factors, including temperature, relative humidity, and AQI. The highest relative risks (RR) were observed at the middle level of temperature and AQI, and high level of relative humidity. The effects for the interaction between AQI and climate factors on HFMD cases were also statistically observed. Compared with low level temperatures (≤23.5 °C), high level temperatures (>23.5 °C) had a RR of 1.486 (95%CI: 1.469,1.503) on days with "good" air quality (AQI ≤ 46), and RR of 1.013 (95%CI: 1.003,1.023) on days with "moderate" air quality (AQI > 46). For relative humidity, the high level (>77%) had a RR of 1.082 (95%CI: 1.076,1.089) on days with "good" air quality, and RR of 1.039 (95%CI: 1.033,1.046) on days with "moderate" air quality. The associations and the interactions remained robust for males and females.

conclusionsOur findings indicate that climate factors and air pollution imposed lagged and non-linear effects on HFMD epidemics. The effects of climate factors on health potentially vary by AQI. Our study is practical and useful for targeted prevention and control, and provides environmental-based evidence.
