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
Tongue is a complex, principally muscular structure extending from oral cavity to oropharynx. Hypopharynx extends from the level of hyoid bone and to the level of inferior margin of cricoid cartilage and is divided into pyriform sinus, posterior cricoid region and posterior pharyngeal wall. Lesions that can affect the tongue and hypopharynx include neoplastic, congenital, vascular and infectious etiologies. Imaging provides crucial details for diagnosis and the appropriate management of these lesions. To evaluate the role of MRI in characterisation of benign and malignant lesions of tongue, malignant lesions of hypopharynx and staging the neoplastic lesions. The study was performed on 60 patients suspected of tongue and hypopharyngeal lesions in Dr Ram Manohar Lohia Hospital, New Delhi from 1st January 2021 to 31st May 2022. The study was done on SEIMENS skyra MRI scanner. Radiological characteristics, clinical features were studied and statistical inference was interrogated. Out of 60 patients, 32 were of tongue cancer, 10 of base of tongue cancer, 8 of hypopharyngeal cancer, 8 of hemangioma tongue and 2 of thyroglossal cyst. The mean age of our study population was 42.87 years. The qualitative analysis between diffusion restriction and histopathological examination shows a strong and substantial agreement between the two variables and a p value of 0.0014. The overall diagnostic accuracy of MRI was 85.5% and for CT was 82.5%. MRI plays an important role in differentiation of benign from malignant lesions of tongue and hypopharynx and staging of the malignant lesions. The correlation between MRI and CT findings of malignant lesions of tongue and hypopharynx indicated that both CECT and MRI have high diagnostic accuracy in diagnosing and staging but MRI is better for T and N staging of the malignant lesions with a diagnostic accuracy of 85.5% which was higher than the diagnostic accuracy of CT (82.5%). Thus, in conclusion MRI has a remarkable role in characterization and staging of benign and malignant lesions of tongue and hypopharynx.
