Fig. 2From: Modelling memory decay after injuries using household survey data from Khartoum State, SudanPredicted rates of reported injuries by time since injury in the log-quadratic model involving effect modification by socioeconomic tertile. Values along the y-axis (RR) represent rates, also incorporating the main effect of socioeconomic status, relative to month 1 in the middle socioeconomic tertile. Curves represent the models with a continuous log-quadratic effect and separate points represent the corresponding models with a categorical effectBack to article page
