Pearson correlations and partial correlations (controlling for age, weight and dietary energy) between salt intake and 24 h urinary sodium excretion.

#The salt taste preference was in comparison with general restaurants, 1 to 5 categories corresponded to saltiest to least salty taste;
†Total salt intake was estimated from both non-discretionary salt (3 days dietary records) and discretionary salt (additional salt intake); Na, sodium; Cr, creatinine; Cr corrected Na excretion, urinary sodium to creatinine ratio;
*, p<0.05;
**, P<0.01.
