Role of Diffusion-Weighted Magnetic Resonance Imaging in the Evaluation of Clinically Suspected Cholesteatoma Cases.
Article in Indian journal of otolaryngology and head and neck surgery : official publication of the Association of Otolaryngologists of India, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
To analyze the apparent diffusion coefficient (ADC) values of middle ear and mastoid lesions in Diffusion weighted Magnetic Resonance Imaging (DW-MRI) to arrive at a probable demarcating value to differentiate cholesteatoma from non-cholesteatomatous lesions. Accurate anatomic localization of the lesion was also done using High Resolution Computed Tomography (HRCT) temporal bone. The study cohort consisted of 30 patients who had undergone HRCT, DW-MRI and surgical intervention in clinically suspected cholesteatomatous lesions during the period August 2018 to August 2020.Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy values of HRCT and MRI in relation to intraoperative findings and histopathological findings (gold standard) were calculated and compared using the 2-sided McNemar's Chi Square test. Receiver operating characteristic (ROC) curve was used to predict the cut off value of ADC to differentiate between cholesteatoma and non cholesteatomatous lesions. Total patients were 30 out of which 15 were histopathologically proven cholesteatoma. MR DWI showed 100% sensitivity, 80% specificity, and 90% accuracy in diagnosing cholesteatoma compared to HPE. The probable cut off value of ADC in differentiating cholesteatoma from non-cholesteatomatous lesions was found to be < 1.226 × 10
