Ber-EP4 staining patterns on basal cell carcinomas.
Article in Northern clinics of Istanbul, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
objectiveThis article aimed to study two different parameters of basal cell carcinoma (BCC): First, to analyze the expression of antihuman epithelial antigen (Ber-EP4) on the primary and recurrent BCCs on the head, neck, and other body parts and second, to find Ber-EP4's staining pattern and staining intensities correlation between histological type, demographic data, tumor, and its prognostic parameters.
methodsWe evaluated the Ber-EP4 staining patterns of 201 patients diagnosed with BCC. We analyzed the possible correlation between the tumor's prognostic parameters and the Ber-EP4 staining intensity and its pattern (peripheral, superficial, or diffused).
resultsIn 199 out of the 201 cases, staining was observed. Two cases were unstained. In 25.6% (n=51) of the cases with staining, the staining was weak, on the 25.6% (n=51), it was moderate, and on the 48.8% (n=97), it was severe. The staining pattern was 31.2% (n=62) peripheral, 4.0% (n=8) superficial, 54.7% (n=109) diffuse, and 10.1% (n=20) peripheral and superficial.
conclusionBer-EP4 is the only antibody commonly used for BCC diagnosis; the existence of different staining intensities and patterns in BCC tumor cells in routine dermatopathology practice limit the pathologists. The studies investigating Ber-EP4 staining in BCCs were conducted with very small numbers of cases. In these studies, even the presence of staining in the focal area was considered to be a positive acceptance criterion; the staining intensity and pattern were not evaluated. Therefore, our study is the first study with a high number of cases and the first to include an evaluation of Ber-EP4 staining's intensity and localization.
