Post-COVID recovery is faster after an infection with the SARS-CoV-2 Omicron variant: a population-based cohort study.
Article in Infection, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 papers.
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
purposePost-COVID-19 condition (PCC) poses a substantial burden to affected individuals, health care systems, and society as a whole. We examined factors associated with recovery from PCC, focusing on the vaccination status prior to infection and the virus variant.
methodsOur analyses are based on the population-based cohort study for digital health research in Germany (DigiHero). Respondents who reported a SARS-CoV-2 infection and COVID-related symptoms ≥ 12 weeks post-infection were classified as having PCC. Those with ongoing PCC were followed-up in six-month intervals based on their date of infection. We used a Cox model for interval-censored data to analyze PCC recovery.
resultsAmong the 4,529 respondents with PCC included in our analyses, about 26%, 19%, 36%, and 44% of those infected during dominance of the SARS-CoV-2 wildtype, Alpha, Delta, and Omicron variant had recovered one year after infection, respectively. When stratifying by virus variant, vaccination was not associated with a faster recovery. Conversely, those infected with Omicron (HR = 2.20; 95%CI: 1.96-2.48) or Delta (HR = 1.69; 95%CI: 1.43-2.01) recovered faster than those infected with the SARS-CoV-2 wildtype or Alpha strain.
conclusionAlthough the recovery from PCC is faster for the newer virus variants, still a substantial fraction of those who developed PCC after an infection with the Omicron variant report prolonged persistence of symptoms.
