  1. The significance of Hosmer-Lemeshow test was 0.30 and 0.92 for the models with SGPALS and IPAQ-SF as dependent variables respectively. The Cox and Snell R2 and Nagelkerke R2 were 0.18 & 0.26 for the SGPALS model, and 0.13 & 0.20 respectively for the IPAQ-SF model. SGPALS the Saltin Grimby physical activity level scale, IPAQ-SF international physical activity questionnaire short form, ICU intensive care unit. Statistically significant values are in bold.
