Control BMD refers to average across whole age range 38–77 yr. Probability of coeliac score being less than zero (one-sample -test). ns: not significant. na: not applied. Control data are from [18, 19]. Effect size is an indication of how great the difference is between 2 measurements and is independent of sample size. Above 0.8 indicates a large difference, above 0.5 a medium difference, and below 0.5 a small difference.
