Table 3 Within-image difference of injured limb by time point for peak spatial frequency radius and Mmax%

From: Spatial frequency analysis detects altered tissue organization following hamstring strain injury at time of injury but not return to sport

  Time point relative to injury Within-image difference P-value
[95% Confidence Interval]
PSFR difference (mm−1) Time of injury 0.15 [0.03, 0.25] p = 0.03
[0.02, 0.31]
Return to sport 0.05 [− 0.13, 0.07]
Mmax% difference (%) Time of injury 0.71 [0.64, 0.98] p = 0.04
[0.16, 1.17]
Return to sport 0.31 [− 0.22, 0.49]
  1. Data are presented as median [interquartile range]. Within-image difference was calculated as \(Healthy-Injury\)
  2. P-values derived from separate two-sided Wilcoxon rank sum tests
  3. PSFR peak spatial frequency radius
