Table 1 Results for the photography population

From: Type 3 finger length pattern is associated with total knee replacements due to osteoarthritis but not with hip replacements or hand osteoarthritis in the elderly: The AGES-Reykjavik study

Photography population (n=5170)     
  Knee OA   Hip OA   Hand OA  
  TKR(n=223) No TKR (n=4947) THR(n=316) No THR(n=4854) Severe(n=673) not severe(n=4497)
Age, mean(SD) years 76.9(5.4) 76.4(5.5) 77.9(5.9) 76.4(5.5) 77.5(4.3) 75.4(4.8)
Percent female 64 57 57 65 73 55
BMI, mean (SD) 29.5(4.7) 26.9(4.4) 27.8(4.5) 27.0(4.4) 26.0(4.2) 27.6(4.3)
Finger pattern (visual photographic,%)

  2 30 38 36 38 33 38
  3 61 49 53 49 53 49
  1. The prevalence of type 3 finger length pattern was higher in the population with TKR compared to the population without knee replacement. No such relationship was seen for THR or hand osteoarthritis.
