Distribution (mean (SD)) of HEI-2015 scores and total energy across fall and winter seasons, and pre- and during COVID-19 pandemic^a

	All	By season			By COVID period
		Fall	Winter	P-value	Before Covid-19	During Covid-19	P-value
N of person-days	324	178	146		214	110
Total energy, kcal	1604.2 (639.4)	1663.1 (676.5)	1532.4 (585.2)	0.09	1637.3 (618.0)	1539.8 (677.3)	0.05
HEI, score	45.3 (13.5)	44.8 (13.7)	45.9 (13.3)	0.35	46.6 (14.7)	42.8 (10.6)	0.01

^aBetween-group differences in HEI score and total energy intake were tested by Wilcoxon Mann–Whitney nonparametric test because they were not normally distributed
