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

backgroundThe effect of bile duct tumor thrombus (BDTT) on the postoperative long-term prognosis of hepatocellular carcinoma (HCC) patients is still under debate.

methodsThe PubMed, Embase, Cochrane Library, Web of Science databases were systematically searched to collect the clinicopathologic characteristics, perioperative indices, and postoperative survival outcomes in the BDTT and non-BDTT groups of HCC patients from inception to February 1, 2020. The study outcomes were extracted by two independent investigators.

resultsA total of 15 studies involving 6,484 patients were included. The meta-analysis revealed that the levels of serum total bilirubin and alkaline phosphatase were notably higher in patients with HCC and BDTT than those without BDTT. Meanwhile, HCC patients with BDTT had more aggressive biological characteristics, such as poor tumor differentiation, macrovascular invasion, and lymph node metastasis, as compared to patients without BDTT. The 1-year [odds ratio (OR) 0.39, 95% confidence interval (CI): 0.31-0.48, P<0.01], 3-year (OR 0.33, 95% CI: 0.22-0.51, P<0.01) and 5-year overall survival (OS) rates (OR 0.31, 95% CI: 0.20-0.49, P<0.01) of the BDTT group were significantly worse than those of the non-BDTT group. The hazard ratio of HCC with BDTT was 4.27 (95% CI: 3.47-5.26, P<0.01) within 5 years after hepatectomy.

conclusionsHCC patients with BDTT had worse OS compared to patients free of BDTT after surgery. BDTT may be a potential prognostic factor for HCC patients.
