How to GRADE the quality of the evidence
This multi-dimensional interaction involves metabolic reprogramming, immune microenvironment, organelle crosstalk, and epigenetic regulation of gene expression, ultimately promoting vascular remodeling and collectively driving the pathological process of PH (Ranasinghe et al., 2023)
The mechanism is likely related to reduced caloric intake and metabolic adjustment rather than a direct drug effect
This nuanced position deserves attention
