Note: Adjusted for age, sex, marital status, education level, household income per capita, residential region, smoking status, drinking status, body mass index, and follow-up duration
The number of diseases in each pattern was considered a continuous variable
OR adjusted odds ratio, CI confidence interval
^aThe factor score for each multimorbidity pattern was standardized to a mean of 0 and a standard deviation of 1 and was used as a continuous variable
