Endoscopic ultrasound characteristics of tubercular lymphadenopathy in comparison to reactive lymph nodes.

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
aimTuberculosis is a common disease in India with significant morbidity and mortality. Limited data is available on the description of tubercular lymphadenopathy on endoscopic ultrasound.
methodsRetrospective data of 116 lymph nodes in 113 patients was evaluated at a tertiary care center. Lymphadenopathy in the mediastinum and abdomen were included. The study was aimed at identifying the endoscopic ultrasound (EUS) features of tubercular lymphadenopathy and comparing them with reactive lymphadenopathy in patients with pyrexia of unknown origin.
resultsThe following features were suggestive of tubercular lymphadenopathy (n = 55) as compared to reactive lymphadenopathy (n = 61): hypoechoic echotexture (94.5% vs. 75.4%, p 0.004), patchy anechoic/hypoechoic areas (30.2% vs. 0%, p = 0.000), calcification (24.5% vs. 0%, p = 0.000), sharply demarcated borders (34.5% vs. 9.8%, p = 0.001), pus like material on aspirate (18.2% vs. 0%, p 0.000), and conglomeration of lymph nodes (10.9% vs. 0%, p = 0.009). The tubercular lymph nodes were significantly larger than reactive nodes at long axis and short axis diameter (2.4 ± 1.1 vs. 1.6 ± 0.6 cm, p < 0.001 and 1.5 ± 0.7 vs. 0.9 ± 0.3 cm, p = 0.001 respectively). On cytopathological examination, presence of necrosis (92.7% vs. 0%, p = 0.000) and granulomas (78.1% vs. 0%, p = 0.000) favored tubercular as compared to reactive lymphadenopathy.
conclusionEUS features like hypoechoic echotexture, patchy anechoic/hypoechoic areas, calcification, sharply demarcated borders, conglomeration, purulent aspirate, larger size, and cytopathological presence of necrosis/granulomas are suggestive of tubercular as compared to reactive lymphadenopathy.
