(N Sample Size; SE Standard Error; ^aAlcohol intake (g/day) was assessed three ways: 1) via a single 24-h recall; 2) by determining usual alcohol intakes with the NCI method, an estimate of long-term intake that employed data from two days of 24-h recalls; and 3) via an alcohol intake questionnaire quantifying annual consumption of alcohol)
