a Pearson correlation representing the association between advancing age and physical symptoms. The severity of physical symptoms was positively correlated with advancing age, with a statistically significant association (r = 0.25, 95% CI 0.00–0.46, P = 0.0472). b Comparative analysis of physical symptoms with box plots representing patients aged <65 and ≥65 years. Patients >65 years had a poorer outcome with higher mean score (38.57 ± 26.75) than those <65 years (17.23 ± 19.89)
