This study aimed to retrospectively evaluate the relationship between demographic characteristics, chest CT findings, and laboratory parameters during hospitalization and post-COVID pulmonary function and exercise capacity. The retrospective study included 101 patients who were hospitalized with COVID-19, had CT findings consistent with COVID-19, and completed at least two months after discharge. In the study, Six-Minute Walk Test (6MWT), Pulmonary Function Tests (PFT), thorax CT and laboratory findings were evaluated. Statistical analyses were conducted using SPSS (v25. 0); normality and variance homogeneity were assessed by Shapiro-Wilk and Levene tests, respectively, while group comparisons were performed using Student’s t, Mann-Whitney U, Chi-square, and one-way ANOVA with Tukey post-hoc tests, and correlations were evaluated by Spearman analysis. Patients with severe/critical COVID-19 had significantly higher age, BMI, length of hospital stay, time from diagnosis to admission, ferritin, CRP, D-dimer, neutrophil %, N/L ratio, and Charlson Comorbidity Index, and lower lymphocyte % (p
