The HL confirmed the goodness of fit for the multivariable model (p=0.607). In categorical variables, men were compared with women, obese (BMI ≥30 kg/m2) and underweight (BMI <18.5 kg/m2) patients with patients with BMI greater than or equal to 18.5–29.9 kg/m2, smokers with non-smokers, patients living in supported housing with patients living independently. The patients with certain underlying condition were compared with those without the underlying condition in question.
BMI, body mass index; COPD, chronic obstructive pulmonary disease; HL, Hosmer-Lemeshow; RSV, respiratory syncytial virus.
