1 · What the graph read from it

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.

2 · The registry

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

backgroundOral submucous fibrosis (OSMF) is a chronic, potentially malignant condition of the oral mucosa, predominantly seen in people of Asian descent. The reported malignant transformation rate of OSMF is 7%-13%. In the context of the understanding progression of OSMF, the study of prime molecular expressions is essential. Various markers have received more attention, one of them is E-cadherin. Various factors which promote epithelial-mesenchymal transition (EMT) and inhibit E-Cadherin include Snail1, Snail2, Twist and EF1/ZEB1. The intended study was undertaken to evaluate the possible role of E-cadherin and its regulatory markers Twist1 and Snail1 in OSMF. AIMS AND

objectivesTo evaluate the expression of E-cadherin, Twist1 and Snail1 in OSMFTo evaluate their possible association with malignant transformation of OSMF. MATERIALS AND

methodsHistologically proven 20 cases of each OSMF with and without dysplasia were taken as the study group, 20 normal mucosa as control group and were subjected for immunohistochemical (IHC) expression with E-cadherin, Twist1 and snail1.

resultsImmunohistochemical expression of all the three markers showed statistically significant expression of all the three markers. Intensity and percentage of staining between the groups were statistically significant for E-cadherin between normal oral mucosa (NOM) and OSMF with dysplasia (OSMFD), no significance was found between NOM and OSMF, whereas Snail1 and Twsit1 were statistically significant between NOM and OSMF and also between NOM and OSMFD. However, no significance was found for all the three markers when compared between the groups OSMF and OSMFD.

conclusionThe increased expression of Snail1 and Twist1 with concomitant loss of E -cadherin in OSMF suggests the role of the EMT.
