Hospitalization flow chart in hemodialysis patients, portraying the selection of the study population.
CVDs: cardiovascular diseases; HD: hemodialysis.

Patient and hospitalization characteristics of patients who received hemodialysis at least 3 times a week.
Fig 2.
Distribution of hospitalization according to the day of the week of treatment for the Monday-Wednesday-Friday and Tuesday-Thursday-Saturday hemodialysis schedules.
(A, B) All-cause, cardiovascular diseases, and infectious diseases in patients receiving hemodialysis in the (A) Monday-Wednesday-Friday and (B) Tuesday-Thursday-Saturday schedules. (C, D) Each type of cardiovascular disease in patients receiving hemodialysis in the (C) Monday-Wednesday-Friday and (D) Tuesday-Thursday-Saturday schedules. The dotted lines indicate the average rate of hospitalization on all the days of the week (1 out of 7 [14.3%]). CBVD: cerebrovascular disease; CVD: cardiovascular disease; IHD: ischemic heart disease; PE: pulmonary edema; VD: vascular disease.
Fig 3.
Generalized estimating equations of the day of the week as a predictor of hospitalization for each type of cardiovascular disease in the Monday-Wednesday-Friday and Tuesday-Thursday-Saturday hemodialysis schedules.
The odds of hospitalization for each type of cardiovascular disease for a given day of the week were compared with those for all the days of the week. Analysis adjusted for age and dialysis vintage at admission. Markers are shown for variables (types of cardiovascular diseases) in each schedule. Shaded markers indicate statistical significantly higher ratios (P < 0.05). Absent markers indicate the variables that did not reach statistical significance. Error bars indicate 95% confidence intervals. CBVD: cerebrovascular disease; Fri: Friday; IHD: ischemic heart disease; Mon: Monday; PE: pulmonary edema; Thu: Thursday; Tue: Tuesday; Sat: Saturday; Sun: Sunday; Wed: Wednesday; MWF: Monday-Wednesday-Friday; TTS: Tuesday-Thursday-Saturday; VD: vascular disease.
Fig 4.
Time trend of proportion of hospitalization on the first HD day for cardiovascular and infectious diseases.
The black line and markers indicate hospitalization rates for cardiovascular diseases on the first hemodialysis (HD) session days. The grey line and markers indicate hospitalization rates for infectious diseases on the first HD session days. CVDs: cardiovascular diseases; HD: hemodialysis; IDs: infectious diseases.
