Expression of Bcl-2 and MIB-1 Markers in Oral Squamous Cell Carcinoma (OSCC)- A Comparative Study.
Article in Journal of clinical and diagnostic research : JCDR, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
backgroundNeoplasia results from various genetic and epigenetic factors. Our study focused on the pathogenesis which involved an imbalance in various molecular mechanisms which regulated cell proliferation and apoptosis. The anti-apoptotic mechanism is regulated by Bcl-2 gene, while Ki-67 is expressed exclusively in nuclei of proliferating cells. This study was done to evaluate the basic pathologic process which underlay well and poorly differentiated oral squamous cell carcinoma (OSCC). MATERIALS AND
methodsThirty cases of oscc were selected, out of which 11 were well differentiated, 9 were moderately differentiated and 10 were poorly differentiated. Three slides of 4μm thickness were prepared out of each sample, which were then subjected to Hematoxylin and eosin stain (H&E) staining and two types of immunohistochemical (IHC) staining. Immunohistochmical markers used were Ki-67 (proliferative marker using MIB-1 (Molecular Immunology Borstel 1) antibody) and Bcl-2 (anti-apoptotic marker). The number of MIB-1 and Bcl-2 positive cells was calculated from ten different high power fields, by counting the number of positive cells per 50 cells in each field, by making a grid pattern. The overall percentage value for each case was evaluated for MIB-1 and Bcl-2 positive cells. Karl-Pearson's co-relation coefficient was calculated between MIB-1 and Bcl-2 in each group. The aim of this study was to co-relate the expression of Ki-67, a proliferative marker, by using MIB-1 antibody and Bcl-2, an anti-apoptotic marker in various grades of oscc and also to determine whether there was any co-relation between these two markers in the 30 cases of oscc .
resultsA statistically significant increase for MIB-1 and a statistically significant decrease for Bcl-2 was found in well to moderately to poorly differentiated Squamous cell carcinoma (SCC). A statistically significant co-relation was also found between MIB-1 and Bcl-2 in poorly differentiated oscc .
conclusionMIB-1 expression is predominant in well, moderate and poorly differentiated SCCs. Bcl-2 expression is predominant in well differentiated than in moderately and poorly differentiated oscc , which suggested that apoptosis probably played a major role in the early stages of carcinogenesis.
