Table 2.

Serum COMP concentrations (mean with standard deviation in parenthesis) before and 3 time points after total hip replacement (n = 15 patients at t₀, t₁, t₂; n = 10 patients at t₃).

Time points	Absolute sCOMP (ng/ml)	95% confidence interval
Time points	Absolute sCOMP (ng/ml)	Lower limit	Upper limit
t₀	718.96 (135.77)	643.77	794.15
t₁	477.28 (147.27)	395.73	558.84
t₂	732.92 (237.54)	601.37	864.47
t₃	754.88 (255.07)	572.41	937.34

sCOMP – serum cartilage oligomeric matrix protein concentration; THR – total hip replacement; t₀ – 6.2 $\pm$ 10.2 days before THR; t₁ – 7.0 $\pm$ 0.5 days after THR; t₂ – 14.0 $\pm$ 1.7 weeks after THR; t₃ – 52.4 $\pm$ 1.9 weeks after THR.
