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

objectivesAmong potential environmental risk factors for systemic sclerosis (SSc), occupational exposures have received some attention. In this meta-analysis, we examined the association between SSc and occupational exposure to silica.

methodsWe searched Medline, Toxline, BIOSIS, and Embase (1949 and November 2009) for original articles published in any language. Sixteen studies are included in the analysis, of which, 3 are cohort studies, 9 case-control and 4 are of other designs. The combined estimator of relative risk (CERR) and 95% confidence interval (CI) were calculated using fixed or random effect models.

resultsSignificant heterogeneity was detected (I (2) = 97.2%; P < 0.01), and the CERR was 3.20 (95% CI, 1.89-5.43). The CERR for studies in females was 1.03 (95% CI, 0.74-1.44) and was 3.02 (95% CI, 1.24-7.35) for males. The CERR for case-control studies was 2.24 (95% CI, 1.65-3.31) and was 15.49 (95% CI, 4.54-52.87) for cohort studies.

conclusionsThe findings suggest that silica exposure may be a significant risk factor for developing SSc and specifically in males. Further observational studies examining the role of occupational silica exposure in the context of other risk factors are needed.
