Rationale

The Farah 2021 article is a high-quality systematic review specifically designed to provide the evidentiary basis for the 2022 SVS/AVF/AVLS joint guidelines. Integrating this citation reinforces the existing recommendations for endovenous ablation. I also expanded all abbreviations (SVS, AVF, AVLS, GSV, SSV, CEAP) on their first use in this section to comply with the formatting rules.
