Increase in physical activity is associated with an increase in sleep efficiency, but not with improvement in symptoms of PTSD: analysis of longitudinal data in trauma-affected refugees

Table 3 Multiple regression analyses of baseline level of physical activity on PTSD symptoms (HTQ), quality of sleep (PSQI), quality of life (WHO-5), and sleep efficiency (SE) adjusted for age and sex
