Table 4. Hazard ratio for dementia comparing hemodialysis and peritoneal dialysis in various analytical models.

	Outcome of dementia comparing hemodialysis and peritoneal dialysis (peritoneal dialysis as reference group)
Various analytical models	Crude HR (95% CI)	Subdistribution HRa (95% CI)
Model 1	1.241 (1.069–1.440)	1.302 (1.128–1.504)
Model 2	—	1.060 (0.918–1.225)
Model 3	—	1.086 (0.940–1.255)

^ause the competing risk approach.

Model 1: use the competing risk approach.

Model 2: adjustment for age, sex, urbanization level, socioeconomic status, and use the competing risk approach.

Model 3: adjustment for baseline propensity score and use the competing risk approach.
