GAD1 and heart failure: In Table 4, Spearman correlation analyses showed that GAD scores (r=-0.423, P < 0.001), PHQ scores (r=-0.353, P < 0.001), and social frailty scores (r=-0.269, P < 0.001) were negatively correlated with the PHE-s® phase, whereas the PAM® scores (r = 0.234, P < 0.001) were positively correlated with the PHE-s® phase in heart failure patients.
