Two typical load–displacement curves. The black one is selected from the control group, and the gray one is selected from the CAI group. Linear regression’s slopes were utilized to calculate load–displacement ratios at different load intervals. Notice that the slope of the CAI is steeper than the control, indicating greater laxity.
