By Raphael Medang,& Dr Gbaguidi Emmanuel RESULTS (1)

By Raphael Medang,& Dr Gbaguidi Emmanuel IMMEDIATELY BEFORE STOCK- OUT 1.Average quarterly sales (μ 1 ) : ,2 (CI 95% μ 1 = [106167,9 ; ,8]) 2.Interquartiles range : [25200 – ]. 3.Standard Deviation (S m1 ): 42534, regions out of 45 (75.6%) had levels of sales < to μ 1. IMMEDIATELY AFTER STOCK- OUT 1.Average quarterly sales(μ 2 ) : ,9 (CI 95% μ 2 = [54201,3; ,4]) 2.Interquartiles range : [18000 – 85800]. 3.Standard Deviation(S m2 ): 29303, regions out of 45 (84.4%) had levels of sales < to μ 2. PARAMETERS OF THE DISTRIBUTION (1)

By Raphael Medang,& Dr Gbaguidi Emmanuel PARAMETERS OF THE DISTRIBUTION (2) The difference in the means before and after stock-out was: (CI 95% μ 1 -μ 2 = [19210,9 ; ,8]) Standard deviation of the difference (S md ): 29942,6 Z = 2,60 (p<0,01).

By Raphael Medang,& Dr Gbaguidi Emmanuel Availability of condoms, higher in the quarter preceding stock-out, than in the one starting resumption of supplies. 1.High dispersion of the sample; 2.Probably not a single control measure taken at first suspicion of stock-out.
