| LDL-real, mg/dL | 82.2 (58.3, 116) | 82.1 (66.2, 102) | 81.2 (65.5, 101) | 0.99 (0.92, 1.07) | 0.782 |
| LDL1+2 cholesterol, mg/dL | 29.6 (18.7, 46.6) | 28.1 (19.7, 40.1) | 33.6 (23.5, 48.0) | 1.20 (1.04, 1.37) | 0.016 |
| LDL3+4 cholesterol, mg/dL | 49.7 (31.8, 77.6) | 50.8 (38.1, 67.8) | 45.1 (33.8, 60.1) | 0.89 (0.79, 0.99) | 0.044 |

| HDL3 cholesterol, mg/dL | 34.8 (28.6, 42.4) | 34.9 (31.4, 38.9) | 35.1 (31.5, 39.1) | 1.00 (0.95, 1.06) | 0.877 |
Values for baseline are geometric means (−1 SD, +1 SD); values for USDA-CON and USDA-LB are least-squares geometric means (−1 SD, +1 SD); values for USDA-LB:USDA-CON are least-squares geometric mean ratios (95% CI); n = 32. P values are for USDA-LB vs. USDA-CON. USDA-CON, a USDA Healthy US-Style Eating Pattern, as outlined by the 2015 Dietary Guidelines for Americans (5), containing <40 g/d red meat; USDA-LB, a USDA Healthy US-Style Eating Pattern, as outlined by the 2015 Dietary Guidelines for Americans (5), modified to incorporate an additional 150 g/d of fresh/unprocessed lean beef to that of the USDA-CON diet, in place of carbohydrate, primarily refined starches.
