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
Aims: Gastrointestinal stromal tumors (GISTs) are neoplastic lesions that primarily affect the digestive tract and develop from interstitial cells of Cajal. These lesions require histopathological and immunohistochemical characterization due to their malignant potential and personalized treatment. In this investigation, the sex, age, lesional sites of origin, histopathological types, the prevalence of human epidermal growth factor receptors (HER-2) expression, prognostic indices (based on tumor size and mitotic figures), expression of CD117 and DOG1, and characteristics of patients with GIST were all characterized. Materials and Methods: This was a retrospective cross-sectional analysis of GIST cases seen at four tertiary health-care centers in Nigeria over a 10-year period (2008-2017) and investigated utilizing histopathological and immunohistochemical (CD117, DOG1, and HER-2) methods. Results: In this investigation, there were twenty GIST cases. Notably, the majority (40%) of the cases had tumors with sizes between 7.0 and 8.0 cm; the stomach was the most frequent site (70%) and the spindle cell type of GIST was the most prevalent (80%) histopathological type. In addition, the stomach was significantly associated with GIST as an origin site (with a P = 0.001), and 100% and 50% of these tumors were immunoreactive with CD117 and DOG1, respectively. Conclusions: In our study, GISTs most frequently develop in the stomach, and CD117 and DOG1 are essential for correctly diagnosing these tumors. However, HER-2 immunoreactivity is a predictive marker of survival for personalized care.
