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

purposeTo evaluate the surgical outcomes of patients with gallbladder cancer (GBC) with jaundice due to as-yet unelucidated prognostic factors.

methodsA total of 348 GBC patients underwent resection at our institute between 1985 and 2016. Of these, 67 had jaundice (serum total bilirubin ≥ 2 mg/dL). Preoperative biliary drainage was performed, with portal vein embolization as required. All patients underwent radical surgery. We retrospectively evaluated the outcomes, performed multivariate analysis for overall survival, and compared our findings to those reported in the literature.

resultsThe 5-year survival rate of M0 (no distant metastasis) GBC patients with jaundice, who underwent resectional surgery, was 21.9%, versus 68.3% in those without jaundice (p < 0.05). Since 2000, surgical mortality in GBC patients with jaundice has decreased from 12 to 6.8%. Patients with jaundice had more advanced disease and underwent major hepatectomies and vascular resections; however, preoperative jaundice alone was not a prognostic factor. Multivariate analysis of jaundiced patients revealed that percutaneous biliary drainage (PTBD) (vis-à-vis endoscopic drainage [EBD], hazard ratio [HR] 2.82), postoperative morbidity (Clavien-Dindo classification ≥ 3, HR 2.31), and distant metastasis (HR 1.85) were predictors of poor long-term survival. The 5-year survival and peritoneal recurrence rates in M0 patients with jaundice were 16% and 44%, respectively, for patients with PTBD and 39% (p < 0.05) and 13% (p = 0.07) for those with EBD.

conclusionM0 GBC patients with jaundice should undergo surgery if R0 resection is possible. Preoperative EBD may be superior to PTBD in M0 GBC patients with jaundice, although further studies are needed.
