Islet response to photobiomodulation varies with the nature of the stress: insights from hypoxia-reperfusion.
Article in Lasers in medical science, 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
Photobiomodulation (PBM) has been shown to protect pancreatic islets under inflammatory or metabolic stress, but its effects during hypoxia-reperfusion remain unclear. We evaluated PBM applied as preconditioning or during hypoxia-reperfusion in MIN6 cells and rodent islets. Hypoxia significantly reduced viability and glucose-stimulated insulin secretion, while PBM failed to prevent these alterations and did not modify mitochondrial parameters. These findings indicate that PBM efficacy is stress-dependent and suggest limited benefit in the context of hypoxia-reperfusion, where mitochondrial dysfunction appears minimal in islet cells.
