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 aim of this study was to compare the clinical outcomes between patients with preoperative cholangitis and noncholangitis patients to determine whether the preoperative cholangitis would be able to serve as an independent predictive factor on hilar cholangiocarcinoma (HCC) outcomes.

methodsA systematic literature search for reported preoperative cholangitis in patients with hilar cholangiocarcinoma was performed in 4 databases: PubMed, Web of Science, Embase, and the Cochrane Library, published from 1979 to 2017.

resultsIn total, the initial search identified 1228 articles. Of these studies only 9 studies met the inclusion criteria and were included in this analysis. Differences between preoperative cholangitis existing and noncholangitis patients were observed in terms of mortality (RR = 2.29; 95% CI = 1.48-3.52; P = .0002), overall morbidity (RR = 1.15;95% CI = 1.00-1.32; P = .04), Liver failure (RR = 1.15;95% CI = 1.00-1.32; P = .04), Infection (RR = 1.52;95% CI = 1.16-2.00; P = .003), sepsis (RR = 2.40;95% CI = 1.25-4.5; P = .008).

conclusionsThe results lend support to the notion that in hilar cholangiocarcinoma patients, the existence of preoperative cholangitis is statistically associated with the higher postoperative mortality and morbidity. Also that it increases the risk of liver failure and infection. therefore, it is very important to properly control the preoperative cholangitis before surgery.
