Treatment effects during the first postoperative year
Upper three panels: Effect-estimates with 95% confidence intervals and p-values for the outcomes DTP, FIM and pain at each time point. The effect for DTP is expressed as the percentage difference in median. The effect for FIM is the difference in the mean change from baseline. The effect for pain is the difference in mean VAS score. The effects refer to the difference AMIS minus LAT
Lower panel: Percentage of patients with FIM-values equal or above their pre-fracture values
