Rapid pulmonary calcification within 10 days in a COVID-19 patient: a case report.
Article in BMC infectious diseases, 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
backgroundPulmonary calcification typically occurs months to years after chronic infections or metabolic disorders. In contrast, it is exceedingly rare in acute viral pneumonias. We report the first case of rapid intrapulmonary calcification within 10 days of SARS-CoV-2 infection. CASE PRESENTATION: An 82-year-old male was admitted with fever and cough. Chest CT revealed scattered calcified foci with a density of 250 HU. Following antiviral therapy (simnotrelvir/ritonavir) and corticosteroids, the calcified lesions exhibited dynamic changes correlating with the inflammatory status. Specifically, partial resolution in early stages, followed by an increase during clinical deterioration, and persistence at discharge. Laboratory tests excluded metabolic causes of calcification (serum calcium, alkaline phosphatase, and parathyroid hormone were within normal limits).
conclusionCOVID-19 may be associated with rapid pulmonary calcification, with serial CT imaging providing a means to track dynamic lesion changes. The underlying mechanisms and long-term clinical significance remain uncertain and warrant further investigation.
