Are there any studies comparing metformin to standard treatments for endometriosis regarding patient outcomes?

The paper addresses whether there are studies that directly compare metformin with standard treatments for endometriosis on patient outcomes. It reports that although metformin has been associated with potential benefits in endometriosis management, direct head-to-head comparisons with standard therapies are not available from high-quality trials, leading to a lack of definitive outcome evidence. A key limitation emphasized is the absence of such comparative studies, which the paper frames as a need for further research. This paper is centrally about endometriosis — it specifically evaluates whether metformin has been compared against standard endometriosis treatments for patient outcomes and highlights the evidence gap.
