The correlation and agreement between alcohol intake assessed with the AFQs and the 30-DR were obtained using Pearson's correlation coefficient (r), Lin's concordance correlation coefficient (pC), Spearman's rank correlation coefficient(rS), Bland and Altman's limits of agreement (LOA) and Cohen's weighted kappa statistic (Kw).ResultsThe reproducibility of the …
