An exploratory interaction term (KD × ASM burden) showed a nonsignificant trend ( p = 0.128), possibly indicating enhanced KD efficacy in more refractory cases.
Although this unadjusted difference did not reach statistical significance and numerically favored controls, it likely reflects treatment selection and immortal time bias.
