Investigating the lasting effects of SARS-CoV-2 infection and the lung microbiome: no persistent microbial alterations in recovered COVID-19 patients with persistent radiological or respiratory abnormalities.
Article in Access microbiology, 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
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was a global pandemic where infected individuals experienced mild or severe disease. Unfortunately, some patients who experienced severe disease also had lasting abnormalities. The lung microbiome of 38 adult coronavirus disease 2019 (COVID-19) patients with persistent respiratory symptoms and/or radiological abnormalities was analysed. The aim was to investigate whether the lasting radiological abnormalities reported in this cohort were associated with an altered airway. Thirty-six bronchoalveolar lavage fluid samples from patients underwent 16S rRNA gene amplicon sequencing and were compared to 28 non-fibrotic control samples from a previously published study. COVID-19 patients had statistically significantly greater number of genera but at uneven abundances, though not statistically significant compared to non-fibrotic controls. Permutational ANOVA (PERMANOVA) suggested that COVID-19 can influence the lung microbiome composition after accounting for multivariate dispersion. Further analysis showed differences in the relative abundances of
