1 · What the graph read from it

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.

2 · The registry

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: Immunocompromised individuals are infected with persistent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and often refractory to treatment. Case Summary: A 56-year-old woman undergoing chemotherapy for follicular lymphoma experienced relapsing pulmonary infiltrates and a consistently low cycle threshold value of nasal swab SARS-CoV-2 PCR over a 5-month period. Despite repeated remdesivir and glucocorticoid therapy, her respiratory symptoms worsened and progressed to respiratory failure. Viral genome analysis revealed that the variant strain at onset was XBB, whereas the strains repeatedly detected more than 2 months after onset were XBB.2.3. Conclusion: The genome analysis indicated that genomic mutations accumulate due to continuous XBB infection. The patient recovered after treatment with nirmatrelvir/ritonavir for 20 days.
