Establishing a new staging system for oral submucous fibrosis and correlation of the proposed staging system to traditional histopathological grading: A clinico-histopathological study.

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 &
objectivesOral submucous fibrosis (OSF) is a potentially malignant disorder of the oral cavity leading to reduction in mouth opening. Mouth opening assessment is used as one of the methods to assess the severity of the disease. In this study the normal maximum mouth-opening capacity of an individual is considered in assessing the reduction in mouth opening. This study was done to establish a new clinical staging pattern in OSF and to evaluate the relationship between the proposed staging system and traditional histopathological grading system of OSF. MATERIALS AND
methodsThe study included 50 clinically diagnosed OSF patients. Normal mouth opening was established by measuring three-finger index (TFI). Existing maximum mouth opening was established by measuring the interincisal distance. Presence of palpable vertical bands was recorded. Histopathological grading was done according to Pindborg and Sirsat. Percentage of reduction in mouth opening (PRMO) was calculated and the mean of PRMO in different clinical and histopathological stages was analysed by fisherman's extract test. A new staging pattern for OSF was proposed from the data.
resultsPRMO was assessed at different clinical stages. A range between 16% and 47% was obtained, and statistically the
conclusionWith the data obtained from our study, the following clinical staging pattern can be adapted: stage I indicates that the PRMO is <30%, Stage II between 30-45%, and stage III >45%. Hence it may be appropriate to asses the disease severity and stage by assessing the degree of disability (i.e., mouth opening reduction considering the individual normal mouth opening ability). The determination of PRMO may be a useful tool in this direction.
