Assessment Explanation
The authors correctly use 'further studies are needed' to indicate uncertainty. No safety conclusion is drawn, so the claim is appropriately framed as a research gap.
Gold Standard Evidence Needed
According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.
Evidence from Studies
