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
Alpha-fetoprotein (AFP) is commonly produced by hepatocellular carcinoma and yolk sac tumors, while AFP in colorectal cancer (CRC) is a rare association. We report a case of a patient with primary AFP-producing CRC, which was successfully treated with surgery and adjuvant chemotherapy. This case highlighted the importance of recognizing a case of AFP-producing CRC. This case report discussed a 59-year-old male who had a history of hepatitis B infection, with two months of intermittent fresh per rectal bleeding. Given his previous burden of hepatitis B infection, and the serum AFP level on admission was high (212.6 ng/mL), this raised suspicions of possible hepatocellular carcinoma. Therefore, a triphasic computed tomography of the liver was performed, which revealed an incidental hepatic flexure lesion with no involvement of the liver. Subsequent colonoscopy revealed a large friable tumor obstructing the whole lumen of the proximal transverse colon. He then underwent an emergency extended right hemicolectomy. Histopathological examination showed a Duke C mucinous adenocarcinoma (T3N2b), with a satisfactory resected margin. Immunohistochemical analysis indicated that the tumor exhibited positivity for MLH1/MSH2/MSH6/PMS2 (+++) and human epidermal growth factor receptor 2 (HER2), and notably, it also stained positive for AFP. The postoperative period was uneventful, and serum AFP level eventually normalized. The patient completed eight cycles (four months) of adjuvant chemotherapy with capecitabine and oxaliplatin (CAPOX) regimen. A follow-up CT scan and colonoscopy showed no evidence of local or distant recurrence after 12 months of surveillance. AFP may be useful for not only hepatocellular carcinoma but also CRC. In particular, this case report has fully demonstrated the unexpected incidence and emphasized the importance of early recognition and appropriate treatment to prevent potential oversights in the diagnosis of CRC.
