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

backgroundLittle is known regarding the risk of tumor dissemination when percutaneous biliary drainage is used before surgical resection of perihilar cholangiocarcinoma (PHC). We aimed to compare the incidence of tumor dissemination after preoperative endoscopic nasobiliary drainage (ENBD) with that after percutaneous transhepatic biliary drainage (PTBD) for PHC.

methodsData from 208 consecutive patients who underwent PHC resection between 2000 and 2013 were retrospectively analyzed. The influence of drainage type on incidence of tumor dissemination was examined. Seventy-six patients underwent ENBD (37%), 87 underwent PTBD (42%), and 45 underwent surgery without preoperative biliary drainage (WD, 22%).

resultsThe respective 2- and 5-year estimated cumulative incidences of tumor dissemination in the ENBD group (11.8/14.6%) were lower than in the PTBD group (28.8/35.9%, p = 0.003) and equivalent to that in the WD group (11.2/15.9%, p = NS). PTBD (hazard ratio [HR] vs. ENBD, 2.80) was an independent risk factor for postoperative tumor dissemination in the multivariate analysis. The 2- and 5-year disease-specific survival rates were higher in the ENBD group (67.6/47.3%) than in the PTBD group (56.6/27.8%, p = 0.032) and equivalent to that in the WD group (64.9/53.8%, p = NS). However, drainage type was not an independent risk factor in multivariate analysis of disease-specific survival.

conclusionFor patients with PHC, the associated risk of postoperative tumor dissemination in the ENBD group was lower than in the PTBD group and equivalent to that in the WD group. Thus, ENBD is the ideal procedure for preoperative biliary drainage.
