A Zinc Chelate of Lysine/Glutamic Acid Reduces Alcohol-Induced Ciliary Dysfunction.
Article in Biology, 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
Alcohol misuse is a known risk factor for pneumonia, and up to 50% of individuals who misuse alcohol are zinc deficient. Chronic alcohol misuse can lead to alcohol-induced ciliary dysfunction (AICD), preventing effective mucociliary clearance and protection against lung infection. Because zinc salts fail to alter AICD, we hypothesized a form of zinc (Zinpro Zinc LG) with enhanced cell uptake would protect against AICD. Human and mouse airway epithelial cells were treated with 50 mM ethanol for 1-24 h followed by the ciliostimulatory agents. Cilia beat frequency (CBF) and cAMP-dependent protein kinase (PKA) activity were assayed. Cyclic AMP or beta agonists stimulated a significant increase in CBF, but 24 h alcohol pretreatment resulted in the desensitization of the cilia to these agents. Pretreatment of cells with 1-10 µg/mL Zinpro Zinc LG prior to alcohol restored the cAMP cilia stimulation response. Zinpro Zinc LG alone produced no effects and was not toxic at <10 µg/mL. PKA activation was prevented in cells treated with alcohol for 24 h, but pretreatment with Zinpro Zinc LG prior to alcohol restored kinase activation. Zinpro Zinc LG prevented alcohol-stimulation of Protein Phosphatase-1, the regulator of PKA desensitization. These data demonstrate that the exposomal combination of alcohol and nutritional Zn deficiency could lead to an aberrant ciliary clearance response that may be prevented by effective zinc supplementation.
