Belli and Vanacore estimate standardised proportionate mortality ratios for a number of causes of death for 24,000 Italian soccer players active in the period 1960-1996.
To be included in this meta-analysis, studies had to report estimates of the relative risk (RR), odds ratio (OR), standardized incidence ratio (SIR), standardized mortality ratio (SMR), proportionate mortality ratio (PMR), or proportional registration ratio with corresponding 95% confidence intervals (CIs) for ever-versus-never occupation as a painter or have provided enough information that allowed for their computation.
In total, we included in the meta-analysis 17 cohort and record linkage studies, 29 case-control studies, and 12 proportionate mortality analyses.
who extracted data that included authors, publication date, country of origin, characteristics of the study population including sex, and any details on the definition of painters, incidence versus mortality, lung cancer histology, observed and expected cancer cases (for cohort and proportionate mortality studies), number of exposed cases and controls (for case-control studies), yes/no adjustment for smoking or other occupational carcinogens, relative risks with corresponding 95% CIs, and results on exposure-response [see Supplemental Material, Tables 1-3 (doi:10.
Wherever possible for the proportionate mortality studies, we used proportional cancer mortality ratios (calculating expected proportions of cancer deaths based on the proportion of cancer mortality in the reference population) in the analysis instead of PMRs as a more conservative approach, because proportional cancer mortality ratios provide a better risk estimate for specific cancer sites when the PMR for all cancer is artificially inflated by a deficit in other causes of death (Dalager et al.
We performed a separate meta-analysis for proportionate mortality studies.
Although the results of 13 proportionate mortality studies were not included in the combined analysis, they also demonstrated a significantly increased risk of lung cancer in painters (meta-PMR, 1.
05; Table 1), but there was no difference in proportionate mortality between habitats (ANOVA: [F.
An excess of deaths from nasopharyngeal cancer was also observed in a proportionate mortality analysis of the largest U.
The measure of effect was the proportionate mortality ratio (PMR), using all the other deaths in the United States as the comparison group.
