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
Corneal neurosensory abnormalities cause pain and discomfort in ocular surface disease, yet their pathophysiology is poorly understood. Here we show that in a mouse dry eye model, the ocular (over)activation of transient receptor potential vanilloid 1 (TRPV1) channels in response to tear deficiency and tissue damage promotes neuroinflammatory gene expression and macrophage reactivity in the trigeminal ganglion, where the cornea-innervating sensory neurons are located. This is accompanied by ocular surface macrophage activation, impaired corneal sensitivity to mechanical and non-TRPV1-mediated chemical stimulation, reduced corneal nerve density and the sensitization of ocular TRPV1 channels, thus establishing a vicious neurosensory cycle. Isolated corneal TRPV1 activation without ocular desiccation recapitulates macrophage reactivity, corneal nerve degeneration and trigeminal neuroinflammation, whereas the ocular substance P blockade reverts most of the TRPV1-driven corneal neurosensory abnormalities. Our study identifies a corneal-trigeminal axis that facilitates corneal neurosensory dysfunction and suggests potential targets for the treatment of ocular surface disease-associated corneal neuropathy.
