Immunohistochemical Expression of the Stem Cell Marker CD133 in Colorectal Carcinoma.
Article in Cureus, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Background Colorectal carcinoma (CRC) is the second-leading cause of cancer-related death. Despite the combined (surgery, chemotherapy, radiotherapy, and immunotherapy) modalities of treatment, the prognosis remains poor, mostly because of recurrence and distant metastasis. Cancer stem cells (CSC) are thought to be responsible for the development and spread of tumors. Hence, targeted therapy against these cells hopes to reduce the chance of recurrence and metastasis and improve the prognosis. Many immune markers have been identified to detect CSC in CRC. Here, we tried to assess the immunohistochemical expression of the stem cell marker CD133 in colorectal carcinoma and its correlation with various pathological parameters. Methodology A total of 51 cases of CRC were analyzed. Immunohistochemistry for CD133 was done after standardization in our laboratory. Expression status was decided based on the total score obtained by multiplying the intensity score by the percentage score. CD133 expression was correlated with the age and gender of the patient, tumor location, histological grade, extent of invasion, lymphovascular invasion (LVI), perineural invasion (PNI), and nodal status. Results High CD133 expression was seen in 21 (41.17%) cases. There was no significant association between CD133 expression and the pathological parameters except the tumor site. CD133 expression was significantly higher as we moved from the proximal colon to the rectum. Conclusions CD133 expression was significantly higher in the distal part of the large intestine as compared to the proximal part. But there was no linear correlation between CD133 expression and histological grade, extent of invasion, or nodal status.
