*Derived by summing position of woman in tenths of descending carbohydrate intake and tenths of ascending protein intake; score ranges from 2 (very low protein and very high carbohydrate intake) to 20.
†Calculated for all cardiovascular disease outcomes combined; essentially identical for each of indicated cardiovascular disease outcomes, because of their rarity.
