Topical application of nucleotides increase lysozyme levels in tears.

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
The present work studies the effects of topical application of nucleotides on rabbit tear lysozyme levels. Lysozyme values were determined by the diffusion in Agar method described by van Bijsterveld in 1974, and the protein amount was obtained by measuring the inhibitory halos around a Whatman n degrees 1 paper disc of 5 mm in diameter. The tested nucleotides were UTP, Ap(4)A and Up(4)U. These compounds were topically instilled in a single-dose in one eye (with the contralateral eye as a control) and the lysozyme halos were measured along 5 hours. The obtained results showed an increase in the lysozyme concentrations of 67%, 93%, and 119% for UTP, Ap(4)A, and Up(4)U, respectively, over the basal levels of lysozyme. For this reason, we suggest these molecules as a potential treatment for the reinforcement of the tear film barrier against ocular infection.
