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 study reports the feasibility and successful production of rabbit cG-CAOMECS, designed to reconstruct corneal epithelium of patients with bilateral limbal stem cell deficiency. To produce a safe, chemically defined and FDA compliant cG-CAOMECS, oral mucosal epithelial cells were isolated from a biopsy of rabbit buccal tissue and seeded on a cGMP-certified cell culture surface coated with GMP-grade extracellular matrix. A newly designed clinical-grade medium (KaFa™ medium) was utilized to carry out cell expansion. Detachment and harvesting of the produced cell sheet was accomplished using collagenase treatment. Live cell imaging and morphological analysis techniques were used to examine cell growth. Cells attached onto the surface and self-assembled into colony-forming units (CFUs). Microscopic examination showed that CFUs formed during the first 5 days, and basal monolayer cell sheet formed in less than 10 days. Cells expanded to form a multilayered epithelial cell sheet that was harvested after 17-19 days in culture. Immunostaining and Western blot analyses showed that deltaNp63 was expressed in the basal cells and K3/K12 was expressed in the apical cells, indicating the presence of corneal epithelial-like cells in the produced cell sheet. Adhesion molecules, E-cadherin, beta-catenin, and Cnx43 were also expressed and exhibited the epithelial integrity of the cell sheet. The expression of integrin-beta1 and beta4 confirmed that the collagenase treatment used for detaching and harvesting the cell sheet did not have adverse effects. Our results showed that the utilization of clinical-grade and FDA-approved reagents successfully supported the production of cG-CAMECS.
