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

backgroundWe investigated whether the effect of air pollution on daily mortality is enhanced by high temperatures in Wuhan, China, using data from 2001 to 2004. Wuhan has been called an "oven" city because of its hot summers. Approximately 4.5 million permanent residents live in the 201-km(2) core area of the city.

methodWe used a generalized additive model to analyze pollution, mortality, and covariate data. The estimates of the interaction between high temperature and air pollution were obtained from the main effects and pollutant-temperature interaction models.

resultsWe observed effects of consistently and statistically significant interactions between particulate matter < or = 10 microm (PM(10)) and temperature on daily nonaccidental (p = 0.014), cardiovascular (p = 0.007), and cardiopulmonary (p = 0.014) mortality. The PM(10) effects were strongest on extremely high-temperature days (daily average temperature, 33.1 degrees C), less strong on extremely low-temperature days (2.2 degrees C), and weakest on normal-temperature days (18.0 degrees C). The estimates of the mean percentage of change in daily mortality per 10-mug/m(3) increase in PM(10) concentrations at the average of lags 0 and 1 day during hot temperature were 2.20% (95% confidence interval), 0.74-3.68) for nonaccidental, 3.28% (1.24-5.37) for cardiovascular, 2.35% (-0.03 to 4.78) for stroke, 3.31% (-0.22 to 6.97) for cardiac, 1.15% (-3.54% to 6.07) for respiratory, and 3.02% (1.03-5.04) for cardiopulmonary mortality.

conclusionsWe found synergistic effects of PM(10) and high temperatures on daily nonaccidental, cardiovascular, and cardiopulmonary mortality in Wuhan.
