What the source establishes
Sixty-eight insulin-independent adults with type 2 diabetes were randomized to MK-7 or placebo for twelve weeks. The study assessed glucose, insulin and lipid measures. [1]
Fasting glucose and HbA1c favored MK-7. Insulin and insulin-resistance measures improved from baseline within the active group but did not significantly differ from placebo; lipid profiles did not significantly change. [1]
What it does not establish
Within-group improvement cannot substitute for the between-group result. The short trial does not establish prevention of complications, benefit in insulin-treated populations or a personal supplement regimen. Funding and conflicts were not established from the abstract. [1]
A hypothetical distinction
Imagine a measure improves during treatment but improves similarly with placebo. The change over time alone does not establish an added treatment effect.
| Detail | Interpretation |
|---|---|
| Glucose endpoints | Positive comparison |
| Insulin measures | No significant group difference |
| Lipids | No demonstrated lowering |
