Perilobular opacities, parenchymal bands, and mosaic attenuation were more common in post-COVID-19 abnormalities than in either type of ILA (perilobular opacities: 75% vs. 5% and 20%, respectively; p < 0.001; parenchymal bands: 85% vs. 15% and 20%, respectively; p < 0.001; mosaic attenuation: 15% vs. 0% for both ILA types, p = 0.04). Here, TNFRSF9 is linked to COVID-19.
