Scatter plots and best fit lines of linear regression between test forces and micro-architectural parameters (bone surface density) or node number (number of branch points of the cancellous bone network/total volume) on micro-CT and MSCT. a Peak torque versus bone surface density (bone surface [BS]/total volume [TV]) on micro-CT. b Pull-out force versus BS/TV on micro-CT. c Implant stability quotient (ISQ) value versus node number (NNd)/TV on micro-CT. d Peak torque versus BS/TV on MSCT. e Pull-out force versus BS/TV on MSCT. f ISQ value versus NNd/TV on MSCT. N Newton, N m Newton meter, a.u. arbitrary units
