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

backgroundLung is the most common extrahepatic metastatic organ of liver cancer. Surgical resection is a common local treatment for pulmonary metastasis. But the long-term prognosis of pulmonary metastasectomy varies greatly due to the small sample size and different results of previous studies. Therefore, we conducted this meta-analysis to evaluate the combined 5-year overall survival (OS) rate and prognostic factors after pulmonary metastasectomy in liver cancer.

methodsKey words such as liver cancer pulmonary metastasis and metastasectomy were retrieved firstly in PubMed, Cochrane Library, Embase and Chinese Wanfang databases. Eligible studies were identified by manual searches. Each included study should report 5-year OS rate and/or prognostic factors of pulmonary metastasectomy. Newcastle-Ottawa Scale was used for quality assessment, and heterogeneity was estimated by I

resultsSeventeen cohort studies with a total of 513 patients were included in this meta-analysis. The combined 5-year survival rates after pulmonary metastasectomy were 33% [95% confidence interval (95% CI) 29-37%]. The poor prognostic factors were disease-free interval (DFI) < 12 months (HR = 2.421 95% CI 1.384 4.236) and existence of cirrhosis (HR = 1.936 95% CI 1.031 3.636).

conclusionThe 5-year OS rate of patients with pulmonary metastasectomy after resection of primary liver cancer is 33%. DFI < 12 months and existence of cirrhosis are probably poor prognostic factors.
