The Lacritin-Syndecan-1-Heparanase Axis in Dry Eye Disease.
Review in Advances in experimental medicine and biology, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Homeostasis and visual acuity of the surface of the eye are dependent on tears, a thin film comprising at least 1800 different extracellular proteins and numerous species of lipids through which 80% of entering light is refracted at the air interface. Loss of homeostasis in dry eye disease affects 5-7% of the world's population, yet little is known about key molecular players. Our story began as an unbiased screen for regulators of tearing that led to the discovery of homeostasis-restorative 'lacritin', a tear protein whose active form is selectively deficient in dry eye. Heparanase acts as a novel 'on-switch' for lacritin ligation of syndecan-1 necessary to trigger basal tearing, as well as pertussis toxin-sensitive and FOXO-dependent signaling pathways for healing of inflammation-damaged epithelia and restoring epithelial oxidative phosphorylation by mitochondrial fusion downstream of transiently accelerated autophagy. A phase 2 clinical trial has tested the applicability of this mechanism to the resolution of dry eye disease. Results are not yet available. With lacritin proteoforms detected in cerebral spinal fluid, plasma, and urine, the capacity of the lacritin-syndecan-1-heparanase axis to restore homeostasis might have wide systemic relevance to other organs.
