Fig. 1From: Clinical efficacy of sodium bicarbonate in treating pediatric metabolic acidosis with varying level of acid–base balance parameters: a real-world studyIn-hospital mortality curves of children treated with sodium bicarbonate or not, based on varying levels of anion gap and chloride. The ordinate in A and C represents practical in-hospital mortality, the ordinate in B and D represents predicted in-hospital mortality using LOWESS, and the abscissa displays anion gap and chloride after grouping into series.
