Similarly, the serum TIM‐3 level (sTIM‐3) increased at aCOVID compared with HD (3701 IQR 2122–5121 vs. 754 IQR 510–867 ng/mL, respectively; p < .0001) and at post‐COVID‐19 time, sTIM‐3 decreased, but it was still higher than HD, and this behavior was observed in both, post‐COVID‐ILD (1871 IQR 1048–2587 ng/mL) and VC (1815 IQR 1196–2292 ng/mL) groups (Figure 4B). Here, HAVCR2 is linked to interstitial lung disease.
