Efficacy of collagen-silicone bilayer membrane in the management of oral submucous fibrosis: a prospective case series.
Article in Oral and maxillofacial surgery, 2022. 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
BACKGROUND AND
objectiveOral submucous fibrosis is a scourge of Southeastern Asia since a long time resulting in significant health and social problems. Mainstay of the treatment is concentrated on attempts to improve mouth opening and relieve the symptoms by medicinal or surgical means. In moderate to severe cases, release of fibrous bands is advocated followed by placement of graft. The present study was conducted to evaluate the use of collagen-silicone bilayer membrane as a mucosal substitute in its management. METHODOLOGY: Study consisted of 12 clinically and histologically proven cases of OSMF. After the incision and release of fibrous bands, a collagen membrane was placed and secured over the raw area by placement of a silicone sheet of adequate thickness. Parameters were assessed pre-operatively, intra-operatively, and post-operatively at 1 week, 1 month, and 3 months. The data was recorded and statistical analysis was done.
resultsPre-operatively, the mean values of inter-incisal opening, cheek flexibility, and width of oral commissure were 16.92, 24.58, and 53.17 mm respectively whereas at 3 months post-operatively, it was 27.67, 26.58, and 55.00 mm, which was statistically significant. No incidence of infection was noted.
conclusionThe study concludes that the use of collagen membrane along with silicone sheet can be an alternative to other graft materials in context of reduced donor site morbidity as well as significant increase in inter-incisal opening. However, study with more sample size is needed to assess the long-term efficiency and surgical outcome of this material.
