The Utility of BSND Immunohistochemistry in the Differential Diagnosis of Oncocytic and Warthin-like Mucoepidermoid Carcinoma of Salivary Gland.
Article in Head and neck pathology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled it.
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
purposeBSND is a chloride channel subunit that is expressed in the normal salivary gland. We aimed to validate the utility of BSND immunohistochemistry in the differential diagnosis of oncocytic salivary gland neoplasms.
methodsBSND immunohistochemistry was performed in a retrospective cohort of 93 salivary gland lesions, enriched with tumors with oncocytic features and histologic variants of mucoepidermoid carcinoma (MEC).
resultsAll oncocytomas (n = 18) showed diffuse membranous BSND immunopositivity. Warthin tumors (n = 18) were also positive for BSND, but the staining pattern was patchy cytoplasmic and membranous in 10-25% of tumor cells. Using a threshold of 10% BSND-positive cells, all Warthin tumors were positive, while none of Warthin-like MECs or non-MEC salivary tumors were positive. Applying the same 10% positivity criterion, two oncocytic MECs were positive for BSND. The percentage of BSND staining in oncocytic MECs was up to 20%. In contrast, BSND was diffusely positive in oncocytomas with a median percentage of positivity of 95% (range: 40 - 100%). Therefore, a higher threshold of > 20% BSND-positive cells may be considered when differentiating between oncocytoma and oncocytic MEC.
conclusionBSND immunohistochemistry is a potentially useful diagnostic marker for salivary gland neoplasms, especially oncocytic and Warthin-like MECs. A threshold of ≥ 10% positivity can differentiate Warthin tumors from Warthin-like MECs, whereas > 20% positivity can be effective for separating oncocytomas from oncocytic MECs.
