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
backgroundBy evaluating serum Ribonucleotide-diphosphate Reductase subunit M2 (RRM2) levels and mRNA tissue expression, we aimed to investigate the potential role of RRM2 as a prognostic biomarker in Colorectal Cancer (CRC) patients.
methodsThis descriptive-analytic cohort study was conducted on 50 newly diagnosed CRC patients (stage II, III). Real-time PCR determined the mRNA tissue expression of RRM2. Fifty healthy individuals who came to the hospital of Golestan University of Medical Sciences and Tehran University of Medical Sciences for routine check-ups were considered the control group. Serum RRM2 protein was measured using an ELISA method in the patient group before, one month, and three months after the surgery, and in the control group just on the day of a routine check-up. The tumor metastasis node (TMN) classification system and occurrence of liver metastasis were evaluated in CRC patients.
resultsThe RRM2 gene expression ratio and 95% confidence interval (CI) of the cancerous tissue was 6.56 times higher than the normal tissue (p < 0.001). Blood Sugar level (BS) (p < 0.001) and platelet level (PLT [range 0.004-499 × 10
conclusionSerum RRM2 level and mRNA expression were significantly higher among CRC patients which could be considered a biomarker regarding CRC progression.
