Expression of Her2-Neu in Primary Gastric and Gastroesophageal Adenocarcinoma: An Experience from a Tertiary Center in South India.
Article in South Asian journal of cancer, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Gastric cancer is one of the most commonly occurring cancers worldwide, often presenting at an advanced stage. Combining targeted therapy with chemotherapeutic agents can enhance and extend the survival of these patients. This 4-year retrospective study aims to assess the prognostic role of Her2-Neu expression in gastric and gastroesophageal (GE) cancer. Clinicopathological features, histological type (Lauren classification) of adenocarcinoma, and Her2 immunohistochemical expression were correlated with disease-free and overall survival in 114 patients. A Her2 score of 0 and 1+ indicated negativity, while 3+ marked positivity. For cases with a 2+ score, fluorescent in situ hybridization (FISH) was conducted for definitive categorization. Statistical analysis employed IBM SPSS version 20.0 software. Among 114 patients, 13 displayed strong Her2-Neu immunopositivity (3 + ), 9 scored 2 + , and 92 were negative (0 [89] and 1+ [3]). FISH classified 4 and 5 cases as positive and negative, respectively. Most (64.7%) Her2-Neu-positive tumors occurred in the proximal stomach/GE junction (GEJ) and exhibited intestinal morphology (94.1%) with moderate differentiation (
