From: Could KL-6 levels in COVID-19 help to predict lung disease?
Multi-panel describing results. a Comparison of KL-6 levels in healthy subjects, COVID-19 subjects, and ILD-subjects. b Comparison of oxygen levels at admission between high and low KL-6 level patients. High KL-6 patients display a significantly lower SpO2. c Comparison of LDH values between high and low KL-6 level patients. High KL-6 patients display a significantly higher LDH value. d Comparison of PLR (platelets/lymphocyte ratio) between high and low KL-6 level patients. High KL-6 patients display a significantly higher PLR. e Correlation between KL-6 and oxygen levels. f Correlation between KL-6 and LDH levels. Statistics: Data are analyzed by non-parametric unpaired test. a Kruskall Wallis test and with post hoc Dunn-test; b–d. Mann–Whitney test; e, f: Spearman correlation. *P < 0.05; **P < 0.001; ***P < 0.0001. NB: High KL-6 are KL-6 levels for which values are above mean + 2SD
