Table 2 Prediction of the metatarsophalangeal HV angle from the results of the margo medialis pedis method

From: The hallux valgus angle of the margo medialis pedis as an alternative to the measurement of the metatarsophalangeal hallux valgus angle

Prediction of CCC 95% CI Precision Accuracy Shift 95% CI
CC 0.79 0.75 – 0.83 0.90 0.88 4.8 2.9 – 6.7
SB 0.79 0.75 – 0.83 0.89 0.89 4.8 2.8 – 6.8
  1. Concordance correlation coefficient (CCC) and 95% confidence interval (CI), precision, accuracy and shift (absolute bias) with its 95% CI from estimating results of the centre base – centre head (CC) method and the shaft bisection (SB) method from results of the margo medialis pedis method.
