Comparison of DKG-CMR and baseline model performance (Independent samples t-test, cohen’s d = 1.24).

Metric	DKG-CMR	Baseline	Improvement	Mean Diff 95% CI	Cohen’s d (95% CI)
F1-score	0.91***	0.68	33.7%	[0.89,0.93]	1.24[1.01,1.47]
Response time (s)	1.45***	2.97	51.2%	[1.43, 1.59]	1.68[1.41,1.95]

F1-score comparisons were tested by Levene’s chi-square test (F = 2.17, p = 0.14); *p < 0.05, **p < 0.01, ***p < 0.001; response latency is in seconds (s); performance improvement = (DKG-CMR-baseline)/baseline × 100% (refer to IEEE Performance Reporting Standard, 2023)²⁷.
