Percent change in intake between 1980–1982 and 2007–2009.
P for change results from generalized linear mixed model analysis least square means tests comparing 1980–1982 and 2007–2009 intake estimates.
P for trend results from generalized linear mixed model analysis test for linear trends across the survey periods.
