    Life-table estimates of contraceptive failure

    Life-table estimates of the rate of contraceptive failure for oral contraceptives (OCs) that contain chlormadinone acetate (CMA), desogestrel (DSG), dienogest (DNG), drospirenone (DRSP), and levonorgestrel (LNG). The 95% CIs are not shown to avoid overlapping graphic elements. Typically, confidence limits were clearly smaller than ± 0.002 and ± 0.005 in years 1 and 2 and in years 3 and 4.
