Contribution
It reformulates previous evolution equations for TMDs to facilitate comparison with recent literature, highlighting conditions for their compatibility.

Recasts evolution equations to enable direct comparison with recent results.
Clarifies the theoretical consistency of various approaches in TMD evolution.
Abstract
We reconsider the evolution equations for transverse momentum dependent distributions recently proposed by us and recast them in a form which allows the comparison with results recently appeared in the literature. We show under which conditions the obtained results might be consistent with each other.
