General, 21-Day Postoperative Rehabilitation Program Has Beneficial Effect on Oxidative Stress Markers in Patients after Total Hip or Knee Replacement

Table 2

Comparison of blood parameters of the patients with hip or knee endoprosthesis before and after a 21-day general rehabilitation program. The results (n =41) are presented as median (lower-upper quartile) or mean ± SD. Statistical significance was set at .
