Note: C.I. denotes lower and upper limit of 95% confidence interval.
¹Age-comparative perceived health status was dichotomised (reference = worse).
²Smoking status and alcohol drinking pattern were dichotomised (reference = never smoker/drinker).
³Variables were dichotomised chronic health conditions (reference = absence of disease), health problems in previous 30 days (reference = none), doctor consultation in previous 30 days (reference = none), hospitalisation in previous 12 months (reference = none).
⁴Source of healthcare service utilisation was segregated into three tiers (Table 1) (reference = tier 1).
Statistical significance of p-values are denoted by * (p < 0.05), ** (p <0.01) & *** (p < 0.001).
