Table 5 presents the multivariate analyses for the outcomes of accidental falls. Covariates were selected based on their correlation with accidental falls in Table 4, and were included if their probabilities were ≤ 0.001. Multivariate analysis utilized covariates with p ≤ 0.001, which included age, wheelchair in transportation vehicle or dialysis room, walking aids, assistant during transportation, paralysis, primary nursing care requirement authorization, home visit rehabilitation, daycare utilization, orthopedic disease, cerebrovascular disease, serum creatinine (mg/dl), shoes in the dialysis room, and dementia. The multivariate logistic analysis revealed that age, use of a walking aid, and orthopedic diseases and cerebrovascular disease were significantly correlated with falls among all the covariates with p ≤ 0.001 in the univariate analysis (Table 4)
