Published: March 14, 2024

While ground-glass opacity, consolidation, and fibrosis in the lungs are some of hallmarks acute SAR-CoV-2 infection, it remains unclear whether these pulmonary radiological findings would resolve after symptoms have subsided. We conducted a systematic review meta-analysis to evaluate chest computed tomography (CT) abnormalities stratified by COVID-19 disease severity multiple timepoints post-infection. PubMed/MEDLINE was searched for relevant articles until 23 May 2023. Studies with COVID-19-recovered patients follow-up CT at least 12 months post-infection were included. evaluated short-term (1–6 months) long-term (12–24 follow-ups (severe non-severe). A generalized linear mixed-effects model random effects used estimate event rates findings. total 2517 studies identified, which 43 met inclusion (N = 8858 patients). Fibrotic-like changes had highest rate (0.44 [0.3–0.59]) (0.38 [0.23–0.56]) follow-ups. meta-regression showed that over time decreased any abnormality (β −0.137, p 0.002), opacities −0.169, < 0.001), increased honeycombing 0.075, 0.03), did not change fibrotic-like changes, bronchiectasis, reticulation, interlobular septal thickening (p > 0.05 all).
