3.3 Relationship between baseline data and DSI in MHD patients during lockdown
Based on the mean of the median DSI (40) from both surveys, patients were divided into a low DSI (DSI<40) and a high DSI (DSI≄40) group in the second evaluation. We found that patients in the high DSI group had a longer dialysis vintage and lower albumin and Kt/V levels than those in the low DSI group (Table 2). There were no significant differences between the two groups in the percentage of women, age, Kt/V, and hemoglobin, blood urea nitrogen, alkaline phosphatase, serum Ca, serum P, iPTH, ferroprotein, and transferrin levels.
