Fig. 3From: Krebs von den Lungen 6 (KL-6) levels in COVID-19 ICU patients are associated with mortalityKaplan–Meier curves, dashed blue line represents group A; the solid green line represents group B. Upper panel, A and B group patients with SOFA value at admission lower than median SOFA; lower panel, A and B group patients with SOFA value at admission higher than median (SOFA median value = 5). Upper panel, higher cumulative probability of survival on group A compared to group B when SOFA was < 5. Lower panel, similar cumulative probability of survival in both groups (median 6 vs 5 days in group A and group B, respectively). KL-6 was a solid prognostic marker when SOFA lower than 5, while when SOFA was higher than 5, in the most severe patients, its prognostic power was not statistically significantBack to article page
