Fig. 4From: C-reactive protein: quantitative marker of surgical trauma and post-surgical complications in dogs: a systematic reviewC-reactive protein (CRP) concentrations in dogs before and at several time-points after A elective ovariohysterectomy and B surgical treatment of pyometra [9, 18, 19, 22, 25]. Different superscription letters (a, b) represents significant differences between concentrations at different time-points (P < 0.05). When possible 95 % confidence intervals (CI) were calculated from means and standard deviations stated in the studies. When information for 95 % CI calculations were not available, concentration ranges were plotted insteadBack to article page
