Demographic variables and preoperative hematologic values*
| Variable | IV-only (n = 93) | IA-only (n = 93) | Low-dose combined (n = 95) | High-dose combined (n = 95) | p Value# |
|---|---|---|---|---|---|
| Sex (female) | 87 (94%) | 88 (95%) | 83 (87%) | 88 (93%) | 0.261 |
| Age (years) | 73.4 ± 6.2 | 72.3 ±7.4 | 72.6 ± 6.3 | 72.1 ± 6.9 | 0.511 |
| Height (cm) | 152.3 ± 6.1 | 152.6 ±6.5 | 153.7 ±7.3 | 152.7 ± 6.2 | 0.525 |
| Weight (kg) | 62.4 ± 8.6 | 62.3 ±9.6 | 63.1 ± 9.4 | 64.6 ± 10.7 | 0.346 |
| BMI (kg/m2) | 26.9 ± 3.6 | 26.71 ±3.3 | 26.7 ± 3.6 | 27.7 ± 4.2 | 0.194 |
| Preoperative Hb (g/dL) | 13.2 ± 1.2 | 12.9 ± 1.3 | 13.2 ± 0.9 | 12.8 ± 1.3 | 0.124 |
*Data are presented as means ± SD or as number of patients (%); #p values were calculated using ANOVA for continuous variables (age, height, weight, BMI, and Hb) and chi-square test for the categorical variable (gender); IV = intravenous, IA = intraarticular, Hb = hemoglobin.
