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
Although there are various risk factors in the literature, the established primary risk factor for oral cancer is tobacco and betal-nut chewing habits. It is believed that pathogenesis of oral cancer depends on the aetiology. To assess the histopathological grade and Ki-67 expression in tobacco (smoking/smokeless) and non-tobacco (betal nut/pan masala) habitual buccal mucosa cancer. The cross-sectional study was carried out in Regional cancer centre, Tamilnadu. Proliferative marker, Ki-67 expression was determined by immunohistochemistry using biotin-streptavidin method. The study includes 117 buccal mucosa cancer patients (61 male and 56 female). According to WHO grading system, high frequency observed with well differentiated squamous cell carcinoma 48 (41%) followed by moderate 46 (39.3%) and poorly differentiated 23 (19.7%). The cut-off value 50% was used to categorize Ki-67 expression into low and high labelling index (LI); 96 (82%) buccal mucosa cancer and 4 (3.4%) adjacent normal mucosa patients showed high Ki-67 expression. The present study showed highly significant association of histopathological tumor grade and Ki-67 expression by Chi square and paired
