Fig. 1
Data of DAH30 and CCI against absolute FMD grouped by surgery type. A-B Black circles represent the measured data within the respective group, while data of the total group is depicted by unfilled circles. Linear regression was performed and the resulting line (blue) is represented together with its 95% confidence interval (grey area). No significant prediction can be made by the absolute FMD as demonstrated by the R2 and P values. C-D Central tendencies of DAH30 and CCI were compared between patients with reduced versus normal FMD. In all surgery types, no significant differences could be obtained
