  1. AA = Passive abduction angle of the left fourth finger. OR = odds ratio. CI = 95% confidence interval.
  2. Legend: Association between factors measured in early pregnancy on reported back pain with onset during present pregnancy and persisting 3 months post partum in several univariate and one multiple logistic regression analysis (n = 167). The abduction angle of the left fourth finger in early pregnancy and the number of previous pregnancies were significantly and independently associated to the incidence of back pain.
