SummaryThe present study tested if the accuracy of the VFA reading reproducibility is more affected by the statistical tool used or by the reader’s level of expertise in 50 VFA from a population-based cohort, the OstéoLaus study. We found that uniform kappa and instruction reading with the ISCD/IOF VFA reading course both increased the accuracy of the reproducibility.
