For the incident syphilis outcome, the categorical variable for herpes simplex virus prevalence and incidence were not incorporated as their colinearity with HIV an infection interfered with design convergence. Variables with a p-worth of â¤0.twenty had been integrated in the multivariable product. To attain the most parsimonious product, non-considerable variables have been then removed until finally all variables in the product have been significantly associated with the end result of desire with a p-worth of <0.05.Similar analyses were carried out for the final result of syphilis reinfection.
