From: Variability in monthly serum bicarbonate measures in hemodialysis patients: a cohort study
Predicting next month’s bicarbonate level. For a single monthly serum bicarbonate measurement 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 measurements in the following month that remain in the same category or change category are shown. Percentages may not sum to exactly 100 % due to rounding
