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

backgroundAmbient air pollution is a risk factor for stroke and myocardial infarction, possibly because of alterations in coagulation that influence the arterial circulation. Whether air pollution influences diseases associated with peripheral venous thrombogenesis remains largely unknown.

objectivesTo determine the association between air pollution and venous thromboembolic disease (VTE) in a sample of the general population.

methodsA time-series analysis was used to test the association between daily air pollution and VTE hospitalizations in Santiago between 2001 and 2005. Results were adjusted for long-term trends, day of the week and average daily humidex.

resultsFrom a population of 5.4 million, there were, on average, 2.3 admissions for VTE per day. Pooled estimates of relative risk (RR) [95% confidence interval (CI)] of hospitalization for venous disease were: 1.07 (1.05, 1.09) for a 58.4 p.p.b. increase in ozone (O(3)); 1.06 (1.02, 1.09) for a 5.85 p.p.b. increase in sulphur dioxide (SO(2)); 1.08 (1.03, 1.12) for a 29.25 microg/m(3) increase in nitrogen dioxide (NO(2)); and 1.05 (1.03, 1.06) for a 20.02 microg/m(3) increase in particulate matter < or = 2.5 microm in mean aerodynamic diameter (PM(2.5)). For pulmonary embolism (PE) results were: 1.10 (1.07, 1.13) for O(3); 1.05 (1.02, 1.08) for SO(2); 1.07 (1.04, 1.09) for NO(2); and 1.05(1.03, 1.06) for PM(2.5), respectively.

conclusionAir pollution appears to be a risk factor for venous thrombosis and PE, a disease with a significant fatality rate.
