Background: The pandemic of Covid-19 resulted in significant morbidity and mortality, especially in those with pre-existing diseases like diabetes mellitus, cardiovascular diseases, etc., primarily due to extensive pulmonary involvement. The chest radiograph is the first imaging tool used in all Covid-19 patients. Hence, in this study, we attempt to understand and evaluate the role of the chest radiograph in Covid-19 patients with and without coexisting diseases. Materials and Methods: Our study included RTPCR-positive Covid-19 patients with comorbidities (560 cases) and without comorbidities (145 controls), viz. diabetes mellitus, hypertension, coronary artery disease, or thyroid disease. All controls and cases had chest radiographs with simple fractional zonal scores in a predesigned proforma. Statistical evaluation of chest radiograph scores was compared with and within groups. Results: Among the controls, approximately 63.5% revealed pulmonary findings on chest radiographs contrary to 77% among cases. No statistical differences were noted among controls and cases based on age and gender. The presence of pleural effusion was noted as a significant factor affecting the score and hence the prognosis in both controls and cases. Statistically significant differences were noted in SFZ scores between controls and various case groups. Conclusion: Chest radiograph scores in Covid-19 disease are higher in patients with comorbidities at the time of presentation, most marked in those with both hypertension and thyroid disease followed by those with hypertension and coronary artery disease. Lower zone predominance is seen in all patients including those with and without comorbidities. The chest radiograph scores become statistically significant with more than one existing comorbidity.
