Associations remaining in the multivariable linear regression model after stepwise backward elimination.

A multivariable linear regression model with a stepwise backward elimination procedure was adopted in order to identify those explanatory variables, which most significantly influence the study participants' quality of life (QoL) scores. The explanatory variables and indicators of the multivariable linear regression model at each step of the backward elimination procedure are shown in the supporting information (Table S1). The data on sociodemographic factors, parasitology, and QoL of the 187 study participants were collected in the Taabo health demographic surveillance system, south-central Côte d'Ivoire, in June 2010.
