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
Testicular cancer is among the most common solid tumors in young men. Gastrointestinal tract (GIT) metastasis of testicular cancer has been rarely reported. In addition, metastasis occurs most commonly through retroperitoneal lymph nodes. Manifestations like abdominal pain and obstruction can be present if metastasis to GIT was considered. We report here a case of a 34-year-old male who was admitted to our GIT unit complaining of episodic epigastric pain. Computed Tomogram (CT) scan demonstrated a soft tissue like lesion involving the lumen of duodenum. Moreover, the patient had a right radical orchiectomy 18 months prior to the presentation due to a stage IA non-seminomatous germ cell tumor with no lymphovascular invasion and free surgical margins. Esophagogastroduodenoscopy (EGD) revealed a malignant appearing duodenal lesion and biopsy showed that it was compatible with germ cell tumor. Metastatic embryonal carcinoma to duodenum was diagnosed and confirmed by immunohistochemical stains. Then, the patient's situation was discussed and decided to be on a plan of four cycles of chemotherapy regimens. Testicular malignancy metastasis to GIT is uncommon, but it's important to know that there is a contact between GIT and testicular lymphatic drainage through para-aortic lymph nodes. So, even if it's rare to occur, it's still possible, and we should always be concerned about it. Mostly, diagnosis of testicular tumors begins with evaluating tumor markers such as alpha-fetoprotein (AFP), beta-subunit of human chorionic gonadotropin (B-hCG), and lactate dehydrogenase (LDH). But in contrast, all of these markers were within the normal range of their values in our case. Suspicion for metastasis and GIT involvement must be raised when dealing with a young male who had a history of testicular tumor such as embryonal carcinoma which was reported here in our case. That is very essential for avoiding potential complications and saving time in order to start management.
