The study and its comparison
Sixty-three previously untrained men and women completed a program involving 96 workouts. They received whey, soy or carbohydrate supplements; reported total protein intake was higher in the protein groups than the carbohydrate group. [1]
Lean-mass gains averaged 3.3 kilograms with whey, 1.8 with soy and 2.3 with carbohydrate. Fat-mass changes did not differ significantly among groups. [1]
What the finding establishes
This is a comparison of specific diets and preparations during a particular training program. It cannot establish that soy has no nutritional value or that whey is always superior across ages and dietary patterns. Funding and conflicts were not established from the retrieved abstract. [1]
A hypothetical distinction
Imagine a trial compares two preparations under one training plan. Its ordering is not a universal ranking of protein foods.
| Detail | Interpretation |
|---|---|
| Measured outcome | Keep the endpoint specific |
| Study preparation | Not every retail product |
| Remaining uncertainty | Not resolved by a mechanism |
