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 purpose of this study was to evaluate the expression of claudins 1, 3M (membrane-bound), 3S (cytoplasmic), 4, 5 and 7 in vulvar epithelial neoplasia (VIN I-III) and to compare those with invasive vulvar squamous cell carcinoma. Paraffin tissue sections from 73 vulvar neoplasms (12 VIN I, 12 VIN II-III and 49 vulvar carcinomas) were studied by immunohistochemistry for the expression of claudins 1, 3M, 3S, 4, 5 and 7. Claudin 1 stained strongly in all groups, whereas claudin 3M, 3S and 4 immunostaining were moderate in all groups. Claudin 7 stained strongly in all groups. Claudin 3M expression was higher in VIN I compared to carcinoma, while no difference was found between VIN I and VIN II-III or between VIN II-III and carcinoma. Claudin 1 and claudin 3S expressions also showed the same decreasing tendency from VIN towards vulvar carcinoma. Claudin 5 showed only weak staining in VIN I and VIN II-III, and positive expression was also low in the carcinoma group. Expressions of claudins 1, 3M, 3S, 4 and 7 were found in VIN and vulvar carcinoma. Changes in claudin 1 and claudin 3 expression during progression from VIN to vulvar carcinoma suggests a connection with claudin expression and differentiation of vulvar squamous cells. Claudin 5 does not seem to be important in VIN or vulvar carcinoma.
