1 · What the graph read from it

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.

2 · The registry

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/

aimsRibonucleotide reductase subunit M2 (RRM2) catalyzes the production of deoxynucleotide triphosphates, which are necessary for DNA synthesis. RRM2 has been reported to play an active role in tumor progression, and elevated RRM2 levels have been correlated with poor prognosis for colorectal cancer patients. This study aimed to elucidate the prognostic significance of RRM2 protein expression in hepatocellular carcinoma after surgery.

methodsRRM2 protein expression was evaluated using immunohistochemistry in tumor tissues from 259 hepatocellular carcinoma patients who underwent curative hepatectomy.

resultsHigh RRM2 expression was observed in 210 of 259 patients (81.1%) with hepatocellular carcinomas. High RRM2 expression was significantly associated with viral etiology (p=0.035) and liver cirrhosis (p=0.036). High RRM2 expression was correlated with early recurrence (p=0.004) but not with late recurrence (p=0.144). Logistic regression analysis revealed that high RRM2 expression (p=0.040) and intrahepatic metastasis (p<0.001) were independent predictors of early recurrence. High RRM2 expression unfavorably influenced both shorter recurrence-free survival (p=0.011) and shorter disease-specific survival (p=0.002) and was an independent predictor of shorter disease-specific survival (p=0.008).

conclusionsHigh RRM2 protein expression might be a useful marker for predicting early recurrence and may be a marker for poor prognosis of hepatocellular carcinoma after curative hepatectomy.
