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
objectivesThe objective of the study was to evaluate the human epidermal growth factor receptor 2 (HER2) overexpression, clinicopathological features, and factors affecting survival in patients with gastric cancer.
methodsThe study is a retrospective study conducted with 128 cases of gastric cancer who were admitted to Şişli Hamidiye Etfal Training and Research Hospital between 2005 and 2012. Patients' demographic characteristics, performance score, tumor localization, information about surgery, HER2 measurements, histopathological characteristics, stage, treatment features, metastasis sites, and overall survival time were obtained from medical records. Immunohistochemical analysis was performed for HER2 scoring.
resultsThere were 89 (69.5%) men and 39 (30.5%) women in the study group, and the median age of the patients was 64 years. The median survival time of the patients was 24.43 months. The survival rate of the patients was calculated as 35.4±5.9%. Overall survival time was found to be shorter in the group with higher HER2 levels and also those with advanced-stage cancer. The survival rate was found to be significantly lower in patients with perineural invasion and advanced stage. However, the survival rate was not associated with lymphovascular invasion, surgical margin involvement, and HER2 levels. In the multivariate Cox Regression analysis performed to assess the effects of gender, histological subtype, stage, and surgical margin on overall survival, disease stage was found to be the only factor effective on survival. Gender, histological subtype, and the surgical margin did not affect prognosis.
conclusionThe survival rate in gastric cancers was found to be lower in those with advanced-stage disease. Higher HER2 level and the disease stage were associated with shorter overall survival time.
