Intra-patient $\rho$, r, $e_{d,m}^f$—either when pooling all patients and blood samples together (ALL) or specifically for $h_0$ and $h_5$—evaluated between $\mathsf{\Delta }\left[K^{+}\right]$ and ${\widehat{\mathsf{\Delta }}}_{d,m}^f\left[K^{+}\right]$, expressed as median (interquartile range (IQR)), for each model $f\in \{l,q,c\}$, marker $d\in \{d_w,{\widehat{d}}_{w,c}\}$, and estimation rule $m\in \{a,o\}$.
