Table 4 MME Measurement according to chronicity

From: Varus stress MRI in diagnosis of medial meniscal posterior root tear

  Chronicity P valuea
Acute Sub-acute Chronic
Mean ± SD Mean ± SD Mean ± SD
Pre-Varus 2.89 ± 0.47 3.89 ± 0.63 4.72 ± 1.71 0.001*
Post-Varus 4.89 ± 0.75 6.07 ± 1.16 7.02 ± 1.72 0.001*
P valueb 0.000* 0.000* 0.000*  
  1. aComparison of MME measurements among the three types or stages of chronicity was done by using analysis of variance test (ANOVA test)
  2. bComparison between pre-varus and post-varus stress MME measurements in each separated stage was done by using (paired samples T test)
