From: Peak value of serum KL-6 may be useful for predicting poor prognosis of severe COVID-19 patients
Kinetics of the KL-6 (a) and LDH (b) levels in the good prognosis group (n = 108) and poor prognosis group (n = 39). Boxes indicate the median (interquartile range) and whiskers the 10th and 90th percentiles. *p < 0.01, **p = 0.034, ***p = 0.022 by Mann–Whitney U test. Significantly higher levels of KL-6 and LDH at all points except for LDH on day 8 were observed in the poor prognosis group. KL-6 Krebs von den Lungen-6, LDH lactate dehydrogenase
