Multiple regression model with nutrients as the dependent variables. Factors associated with difference in (energy adjusted) daily grams of nutrient intakes from the FFQ (first administration) and 7-day food diary: Regression models were multivariable, with each factor adjusted for all others (⁺ p < 0.05; ⁺⁺ p < 0.001). ¹ Continuous variable. ² Reference category: Men. ³ Reference category: Primary or below. ⁴ Reference category: <1000 Rupees/month.
