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
purposeThe aim of this study was to use computer simulations to generate quantitative insights as to how the characteristics of convex skin barriers might contribute to stomal protrusion or leveling of the peristomal skin when applied to 3 different types of abdomens varying in thickness and tone of the subcutaneous fat. MATERIALS AND
methodsFinite element analysis (FEA) was used to model the interactions of convex skin barriers with 3 different types of abdomens. The skin barriers' depth, slope, tension location, and compressibility were systematically varied, and the model was used to simulate how each combination deformed the peristomal tissue when applied. The results were analyzed using factorial regression analysis to reveal which characteristics of convexity contribute most to generating central and peripheral tension. The influence of flexibility was not measured as our simulation did not capture the bending motion required to flex the skin barrier.
conclusionsDepth and tension location were identified as the most influential factors in promoting central tension, whereas slope and depth most influenced peripheral tension. These findings further our understanding of the 5 main characteristics of convexity and may assist with appropriate selection of convex skin barriers for a person living with an ostomy.
