(A) Waterfall plot showing the acid-base imbalances of individual patients as the magnitude of change at admission to the ICU for scrub typhus; the amplitude of the bars in the waterfall plot indicate the degree of acid-base imbalance (yellow: Absence of acute respiratory failure; gray: Presence of acute respiratory failure); (B) survival analysis according to the risk groups based on acid-base imbalance; there are significant survival differences between the low-risk and moderate/high risk groups (p = 0.038).
