TL;DR: Two dosages of depot-medroxyprogesterone acetate, 100 mg and 150 mg given every 90 days, were compared in two groups of women with regard to effectiveness, reported complaints and reasons for discontinuation, showing little difference in efficacy and side effects.

TL;DR: The analysis suggests how the life-table analysis of discontinuation reasons underestimates the true incidence of vaginal bleeding irregularities in a clinical trial.

TL;DR: Two new methods of analysis of vaginal bleeding diaries are suggested, one of which measures trends over time in the occurrence of specific patterns and, a second, the relation between a woman's current experience and the probability of continuing method use.

TL;DR: There is a high degree of consistency between the reasons given by individual women for discontinuing the contraceptive method and their vaginal bleeding pattern during the 90 days preceding discontinuations, however the data revealed large between-centre differences, both in the incidence of specific patterns, and in the identification by women of bleeding problems as reasons for discontinuation.

TL;DR: The object of the paper is to invite suggestions for suitable methods of presentation and analysis of data concerning the vaginal bleeding patterns of women using different forms of fertility regulation so that the results of studies on methods of fertilityregulation can be better summarized and interpreted.
