Preliminary considerations on 24HDR  In general, the decision on how many days should be covered by 24HDR to obtain a satisfactory estimate of the consumption /intake of specific foods/ nutrients depends on several factors, including the statistical characteristics of the specific variable(s) of interest, including among the others:  Mean consumption/ intake  Between-day variability

Data analysis  Description of the study population (participants in local cohort studies, including 4 EPIC centers)  Distribution of macronutrients, energy and food groups according to 24h dietary recalls (24HDR)  Reliability measures (1st vs 2nd 24HDR)  The study is still ongoing, here we present very preliminary results!
