From: Variability in monthly serum bicarbonate measures in hemodialysis patients: a cohort study
Predicting the next 3-month mean serum bicarbonate level. For each mean serum bicarbonate calculated over a 3-month period and falling within the low (<22 mEq/L), normal (22–26 mEq/L), and high (>26 mEq/L) categories defined by clinical cutpoints, the percentage of mean values in the following 3-month period that remain in the same category or change category are shown. Percentages may not sum to exactly 100 % due to rounding
