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
Our aim for this study was to investigate the correlation and clinical significance between the expression of IGF-II and Bcl-2 in colorectal adenocarcinoma, especially in terms of the metastasis of colorectal adenocarcinoma. Sixty paraffin embedded samples of colorectal adenocarcinoma were selected, and fifteen normal colorectal tissues were used as controls. IGF-II mRNA was detected using in situ hybridization, and the expression of Bcl-2 along with the proliferating cell nuclear antigen (PCNA) protein was detected through immunohistochemistry. The TUNEL assay was used to detect apoptosis. Specimens with a positive cell ratio less than 30% were defined as negative. The levels of IGF-II mRNA and the Bcl-2 protein were significantly higher in colorectal adenocarcinoma (39.64 ± 7.38% and 30.74 ± 7.22%, respectively) than in normal colorectal tissues (22.56 ± 4.21% and 12.17 ± 1.94%, respectively) (P < 0.01). The levels were related to Dukes' stage and lymph node metastases, but were unrelated to patient age, gender, tumor site, tumor size, and tumor differentiation. Also, a negative correlation was observed between IGF-II mRNA and Bcl-2 protein (P < 0.05) during Dukes' stages. In addition, a positive correlation between IGF-II mRNA and PCNA or apoptosis, as well as a negative correlation between Bcl-2 and apoptosis were observed (P < 0.01). There was no correlation between Bcl-2 and PCNA (P > 0.05). The patients detected as IGF-II mRNA (+) and Bcl-2 (-) showed the worst prognosis. The expression of IGF-II and Bcl-2 was correlated with the clinical manifestation of colorectal adenocarcinoma; thus, the assessment of both IGF-II and Bcl-2's status will provide important information regarding the diagnosis and prognosis of colorectal adenocarcinoma.
