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
Squamous cell carcinoma of the oral cavity is the most common malignancy of head and neck cancer in India. With nodal dissemination, there is a significant decrease in survival. This study is aimed at studying the impact of occult metastasis on an estimated overall survival in clinically N0 patients post neck dissection. In a prospective study with 110 patients with squamous cell carcinoma of the oral cavity, clinically N0 with all T stages were included in the study. operated on for both primary and neck followed up for a median of 5 years after completion of definitive treatment. The impact of surgery on patients with occult metastasis was questionable in our study with a difference in estimated overall survival of around 11 months, which was not significant statistically. Subset analysis had shown the correlation of overall survival with a grade of tumor, T stage and depth of invasion which was statistically insignificant. Correlation of occult metastasis with the depth of invasion, T stage was statistically significant. we conclude that even after addressing the neck in clinically N0 patients with oral cancer, there is a difference in the overall survival of the patients with occult metastasis which might not be statistically significant with a p-value of 0.68. We conclude that with neck dissection in patients with occult metastasis, improved survival might not be comparable to pathological N0. Level of Evidence: LEVEL -2.
