Correlation Between Disease Severity and Chest Computed Tomography Findings in Coronavirus Disease 2019 Patients in a University Hospital of Bangladesh-An Observational Study.
Article in Health science reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background and Aims: The world has been devastated by the pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from 2019 to 2023 which necessitated stratifying patients into mild, moderate, severe, and critical categories based on clinical presentation, oxygen saturation, radiological findings, and systemic inflammatory response syndrome (SIRS). This study aimed to quantify lung involvement using high-resolution computed tomography (HRCT) and correlate it with clinical severity and laboratory parameters. Methods: This observational cross-sectional study was conducted at Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh, from July to September 2020. A total of 90 RT-PCR-confirmed COVID-19 patients were enrolled from outpatient and inpatient departments on the basis of clinical and laboratory parameters in accordance with Interim Guidance, 27th May, 2020 on the Management of COVID-19 from WHO. The major CT findings and CT severity score were described by using internationally standard nomenclature defined by the Fleischner Society glossary and peer-reviewed literature on viral pneumonia. CT severity scores were calculated and statistically correlated with clinical severity and laboratory markers including SpO Results: The mean CT severity score was 11.66, with severe cases showing significantly higher scores than non-severe cases (13 vs. 8.87). HRCT scores had a moderate negative correlation with SpO Conclusion: Age, sex, smoking status, and comorbidities had no relation with the severity of COVID-19. HRCT severity score had moderate negative correlation with disease severity of COVID-19. HRCT severity score is also found to have moderate positive correlation with total neutrophil percentage, CRP, and D-dimer; and moderate negative correlation with total lymphocyte percentage. No correlation was also found between increasing CT severity score with the presence of comorbidities. HRCT severity scoring showed a moderate correlation with clinical severity and laboratory markers in COVID-19, supporting its utility in triage and prognostication. Integrating HRCT scoring into clinical evaluations may enhance decision-making and patient management strategies.
