Responses to illness episode (A) and paying for healthcare (B) in four hypothetical scenarios, with stratification by basic monthly salary. Diamonds give the proportion of all valid responses, with 95% confidence intervals as error bars, while coloured bars give the corresponding proportions for the three income groups: those earning S$499 or less (green), S$500 to S$999 (blue) and $S1,000 or more (orange) per month. Symbols *, ** and *** are differences with p < 0.10, p < 0.05 and p < 0.01 by chi-squared test for trend (A) and chi-squared test (B).
