Table 2 Number of genes in each catalytic class showing differential expression between osteoarthritis and fracture groups

From: Degradome expression profiling in human articular cartilage

  P < 0.05 P < 0.01 P < 0.001 P < 0.0001
Aspartic proteases 1 3 3 1
Cysteine proteases 17 15 6 6
Metalloproteases 19 25 23 9
Serine proteases 19 11 6 10
Threonine proteases 3 2 0 0
  1. Numbers of genes showing statistical significance between the two groups (osteoarthritis versus fracture to the neck of femur (NOF)) in each catalytic class. Pairwise statistical analysis between groups was performed using the Mann-Whitney U test.
