RP prevalence was determined by separating just how many teenagers having RP and also the level of adolescents exactly who knowledgeable at least one pregnancy (plus those individuals currently expecting) increased of the 100. RB incidence as well was computed from the isolating the number of adolescents that have RB plus the level of adolescents who experienced at least one livebirth increased because of the 100. Deformalized survey loads was applied if you find yourself figuring the fresh incidence.
We utilized the ptrendi package when you look at the Stata13 to perform Cochran–Armitage testing to find the incidence trend per generation playing with the latest chi-rectangular fact and you will fulfilling the fresh presumptions of an additive design. Cochran–Armitage sample try a changed Pearson’s chi-rectangular take to which assesses the fresh new connection between binary (we.age. RP and RB) and you will ordinal (i.age. 12 months and you can many years) kinds.
