Torque Teno Virus Dynamics in Plasma and BAL of COVID-19 ARDS Patients With and Without ECMO.
Article in Journal of medical virology, 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
Extracorporeal membrane oxygenation (ECMO) is used to manage severe acute respiratory distress syndrome (ARDS) and is associated with immune modulation. Torque teno virus (TTV) has been proposed as a surrogate marker of immune competence, but it remains unclear whether ECMO influences TTV levels. In this exploratory, retrospective, single-center cohort study, TTV DNA was quantified by qPCR in 174 paired bronchoalveolar lavage (BAL) and plasma samples from 50 adults with COVID-19-associated ARDS. Plasma samples from 40 healthy blood donors were included as controls for baseline comparison. We compared TTV loads between ECMO and non-ECMO patients, assessed longitudinal trends, examined BAL-plasma correlation, and explored associations with mortality and secondary infections. Early plasma TTV in COVID-19 ARDS was lower than in healthy controls (3.20 × 10
