Table 2 Comparison of patients’ mean laboratory parameters at admission and postoperative days 1 and 5 ± 2

From: COVID-19: not a contraindication for surgery in patients with proximal femur fragility fractures

POD1 vs 5 ± 2: p = 0.045
F(1.585, 14.261) = 5.644, p = 0.02
Absolute neutrophil count (× 103/mL) 8.46 ± 2.9 8.46 ± 2.4 6.49 ± 2.6 D0 vs POD1: p = 1
POD1 vs 5 ± 2: p = 0.026
F(1.849, 16.645) = 6.733, p = 0.008
Relative lymphocyte count (%) 11.4 ± 3.2 11.2 ± 5.9 16.3 ± 6.1 D0 vs POD1: p = 1
POD1 vs 5 ± 2: p = 0.02
F(1.602, 14.420) = 5.611, p = 0.02
  1. Univariate repeated measures ANOVA with Greenhouse-Geisser correction and post hoc tests using the Bonferroni adjustment (statistical significance set at p ≤ 0.05)
  2. F statistic reported as F(degrees of freedomtime, degrees of freedomerror) = F value, p value)
  3. Only significant outcomes are reported in this table
  4. Abbreviations: D0 admission day, SD standard deviation, POD postoperative day
