Main job categories between patients with membranous nephropathy and the general population of French workers are compared using a Fisher exact test. Differences between groups were considered to be statistically significant when P values were <0.05. ns, not significant.
a
The frequency observed in the membranous nephropathy cohort was used to calculate the frequency (by sex and age groups) of the main job categories for both cohorts.
b
Significant associations.
