Microvascular Dysfunction and Redox Imbalance in Long COVID.
Article in Microcirculation (New York, N.Y. : 1994), 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
objectiveEndothelial and microvascular dysfunction are key features of Long COVID. Disturbances in cellular redox balance, reflected by altered nicotinamide adenine dinucleotide (NAD
methodsMicrovascular function was assessed in 36 patients with Long COVID and 47 age-matched controls using FMSF. NADH fluorescence changes during ischemia and hyperemia were analyzed as markers of endothelial responsiveness. NAD
resultsPatients with Long COVID showed impaired FMSF parameters, including blunted ischemic responses and delayed recovery after hyperemia, indicating microvascular dysfunction. These changes were accompanied by a reduced NAD
conclusionsFMSF provides a clinically applicable tool for detecting microvascular dysfunction in Long COVID. NAD
