Background: Lateral flow assay (LFA) has demonstratedshowed high sensitivity and specificity for diagnosing cryptococcosis. However, its role in predictivepredicting value for the therapeutic efficacy offor pulmonary cryptococcosis (PC) remainswas rarely reportedunderexplored.We conducted a retrospective analysis ofon HIV-negative patientsPC with PC to presentdescribe the clinical profile and identify the potential predictors offor radiological prognosis.Results: All the 168 participants received antifungal therapy with a triazole agent. Of these, 84.5% experienced partial or complete absorption of pulmonary lesions. The results of the gamma test, chisquare trend test, and ordinal logistic regression all indicated that both baseline LFA and changes in LFA after treatment were significant both predictors of imaging prognosis. The degree of radiological improvement showed was inverselya downward trend associated with as the baseline LFA positive grade increased (P for linear-by-linear association: 0.011, Spearman correlation coefficient = -0.17; γ= -0.368, P = 0.045). Patients who experiencedwith a decrease in LFA after therapy had a significantly better radiological outcomesprognosis compared to than those with equal or increased LFA (linear-by-linear association, P = 0.014, Spearman correlation coefficient = 0.188; γ = 0.371, P = 0.012).Moreover,Additionally, favorable outcomes were more likely in casespatients with lesions restrictedconfined toin the right lung.Conclusions: LFA has shows the potential toof monitoring radiological outcomes in of PCpulmonary cryptococcosis.
