Ex vivo μCT results. a Lateral view of defects covered with regularly placed or upside-down membranes. Representative samples of minimal, median, and maximal bone coverage of the defect in the respective groups are shown. b Relative bone coverage of the defect (p = 0.64). c Total new bone volume inside the ROI (p = 0.06). d Mean trabecular thickness (p = 0.03, bars and whiskers represent medians and interquartile ranges, all p-values using Mann-Whitney U test). μCT, micro-computed tomography
