^aAnion gap is the quantity difference between cations (positively charged ions) and anions (negatively charged ions).

^bAnion gap K⁺ (mmol/L) is difference between the concentration of the cations (sodium and potassium), and the measured anions (chloride and bicarbonate).

^cBold styled p values indicate statistical significance.

^*p < 0.05, ^**p < 0.01, ^***p < 0.001.
