Bland–Altman plots assessing the agreement between the total score of Healthy Eating Index-2015 estimated by a 16-day weighed dietary record (DR) conducted over a year and that estimated by a comprehensive diet history questionnaire (DHQ) or by a brief diet history questionnaire (BDHQ) in Japanese women (n = 121; (a) DHQ and (b) BDHQ) and men (n = 121; (c) DHQ and (d) BDHQ). In each season, a 4-day weighed DR was conducted: November and December 2002 (autumn), February 2003 (winter), May 2003 (spring) and August and September 2003 (summer). For each individual, the mean value of the 16-day data was used. The DHQ and BDHQ used in this analysis were conducted before the period of the DR (November 2002). A regression line was added when it was statistically significant (p < 0.05).
