Model 1: cost during the last 6 months; Model 2: cost during the last 3 months; Model 3: cost during the last 1 month and Model 4: cost during the last 1 week. #Reference: (e) Male; (f) <65; (g) URBMI; (h) Unmarried; (i) Junior or below; (j) Home; (k) <3 months in Model 1 and 2, we took the patients survived 7–12 months and 3–6 months as reference, respectively. Results of additional models: Model 1: Age-group: two versus three (OR=1.322, p=0.033, 95% CI=1.022 to 1.710) and Insurance type: three versus two (OR=1.480, p=0.002, 95% CI=1.160 to 1.887); Model 2: Insurance type: three versus two (OR=1.668, p=0.002, 95% CI=1.206 to 2.305); Model 3: Insurance type: three versus two (OR=1.581, p=0.004, 95% CI=1.161 to 2.152) and Model 4: Survival: four versus two (OR=0.554, p=0.017, 95% CI=0.341 to 0.900); five versus two (OR=1.602, p=0.023, 95% CI=1.067 to 2.405) and four versus three (OR=0.640, p=0.048, 95% CI=0.411 to 0.997).
