Table 4 Log-quadratic relationship with time since injury, within tertiles of socioeconomic statusa
From: Modelling memory decay after injuries using household survey data from Khartoum State, Sudan
Tertile of socioeconomic status | Crude injury rate in month 1 before interview (per 100 person-years) (SE) | Regression coefficient of linear term (per month) (SE) | Regression coefficient of quadratic term (per month) (SE) | Estimated probability that an injury is still reported | Estimated time when reporting probability is 0.5 (months)b | |
