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

objectiveTo examine occupational risk for Chronic Obstructive Pulmonary Disease (COPD).

methodsWe randomly recruited 233 subjects aged 55 to 75 reporting a physician's diagnosis of COPD, emphysema, or chronic bronchitis. Interviews assessed cigarette smoking and longest held job, identifying exposure to vapors, gas, dust, or fumes (VGDF). Lung function was assessed in n = 138. Comparison data were derived from a sample of referents without COPD.

resultsVGDF was reported in 123 (53%) of 233 cases versus 577 (34%) of 1709 referents. VGDF was associated with COPD (Odds Ratio [OR] 2.5; 95% CI = 1.9 to 3.4); the population attributable fraction was 32%. In the lung function subset, the FEV1/FVC was <70% in 79 (57%); 35 (44%) reported VGDF associated with an OR = 1.6 (95% CI = 0.99 to 2.6) and population attributable fraction 17%.

conclusionsThese data support an important role for occupational exposures in COPD.
