  1. n absolute number, prev prevalence, RR relative risk, CI confidence interval, CPA chronic polyarthritis
  2. Example: 1488 patients suffering from urinary incontinence are found in the HU-sample, a figure corresponding to a prevalence of 6.3 %; a patient suffering from urinary incontinence has a risk to belong to HU-type A which is 3.9 points higher than the one to belong to the NHU-subsample. The confidence intervals point to statistical significance
