*This table shows the results of subgroup analyses of the relationship between human resources and the risk of hospitalisation according to the presence of a nephrologist, duration of illness and CCI. In this analysis, we adjusted variables such as age, sex, type of insurance coverage, experience of prehospitalisation within 1 year, duration of illness, CCI, type of medical institution, presence of a nephrologist, haemodialysis volume per doctor, number of beds, emergency equipment in the haemodialysis unit, fulfilment rate of criteria for duration of water analysis, number of haemodialysis machines and proportion of medical cost due to CKD. We marked the results with statistically significant values using shadowing.
CCI, Charlson Comorbidity Index; CKD, chronic kidney disease; RR, relative risk.
