Multivariable analysis of factors, including SMM/WT and HGS, associated with IDH
| Variable | OR (95% CI) |
|---|---|
| SMM/WT (%) plus HGS (kg·f) (vs. SMM/WT, ≥36.0 and HGS, ≥19.0) | |
| Either SMM/WT, <36.0 or HGS, <19.0 | 4.44 (1.29–15.33) |
| SMM/WT, <36.0 and HGS, <19.0 | 17.11 (3.47–84.27) |
| Age | 1.00 (0.96–1.04) |
| Male sex (vs. female) | 1.47 (0.45–4.80) |
| DM (vs. non-DM) | 5.68 (2.20–14.65) |
| Cardiovascular comorbiditiesa (yes vs. no) | 2.26 (0.90–5.69) |
| Cardiac index | 0.95 (0.88–1.03) |
| Ultrafiltration per weight | 1.60 (1.18–2.16) |
To classify SMM/WT and HGS, we used the highest value in the low-SMM/WT tertile group (36.0%), and the median value of HGS (19.0 kg•f) showed an OR of 17.11 to IDH compared to that in patients with SMM/WT of ≥36.0% and HGS of ≥19.0 kg•f.
CI, confidence interval; DM, diabetes mellitus; HGS, handgrip strength; IDH, intradialytic hypotension; OR, odds ratio; SMM, skeletal muscle mass; SMM/WT, percentage of SMM to WT; WT, dry body weight.

Cardiovascular comorbidities were chronic heart failure or ischemic heart disease.
