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
In Indonesia, colorectal cancer is the third most common type. In 2008, Indonesia ranked fourth in the Association of Southeast Asian Nations (ASEAN) countries, with an incidence rate of 17.2 per 100 000 population. This figure is predicted to continue to increase from year to year. In 30% of colorectal cancer patients diagnosed after metastases, some patients will develop metastases after undergoing surgical resection of the primary tumor. The survival of metastatic colorectal cancer patients has improved significantly in the last 20 years with the introduction of target-oriented drugs, anti-epidermal growth factor receptor (EGFR), and anti-human epidermal growth factor receptor-2 (HER2). This study aims to assess the relationship between Kirsten rat sarcoma viral oncogene homolog (KRAS) mutation and HER2 expression for targeted therapy implementation. Patients and methods: This research is a cross-sectional study. The research subjects in this study were colorectal cancer patients in the digestive surgery division. There were 58 study subjects. Examination of KRAS mutations was carried out by PCR on fresh tumor tissue obtained from surgery or colonoscopy. Meanwhile, the HER2 examination used the immunohistochemistry method of paraffin blocks for anatomical pathology examination. Results: Examination of KRAS mutations showed 28/58 (43.8%) patients with colorectal cancer, while HER2 overexpression was found in 6/58 (10.3%) patients with colorectal cancer. Univariate analysis of KRAS mutations and HER2 expression showed that four subjects with KRAS mutations had excess HER2 expression ( Conclusion: There is no association between KRAS mutations and HER2 overexpression in colorectal cancer patients.
