Table 4 Estimates of between subject (BS), within subject (WS) and analytical (A) variation (percentages of total variance in brackets), and coefficients of variation (CV) of CRP for men (nind = 92, nobs = 552), non-oral contraceptives (OC) using women (nind = 75, nobs = 300) and oral contraceptives using women (nind = 56, nobs = 224), separately.
