Promising but understudied

Early findings are encouraging, but stronger trials are needed.

Promising areas needing more evidence

Why it matters

Promising signals can guide further review, but they should not be treated as settled evidence.

Interpretation

Dietary fibre supplement (YMETA) may have a beneficial signal, but the evidence base is still developing.

Caution

Current support is limited by study volume, RCT depth, or evidence strength.
