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

The aim of the present study was to compare the effects of percutaneous transhepatic biliary drainage (PTBD) and endoscopic biliary drainage (EBD) for resected malignant obstruction jaundice (MOJ) on the incidence rate of implantation metastasis. Databases including PubMed, EMbase, Web of Science and Cochrane Library were utilized. With reference to literature reported until January 2019, controlled clinical trials were designed to compare the effects of PTBD and EBD for MOJ on the incidence rate of implantation metastasis. Subsequently, odds ratio (OR) with 95% confidence interval (CI) was calculated with Review Manager 5.3.0 software. A total of 10 studies were enrolled in this meta-analysis, including 1,085 cases in the PTBD group and 1,379 cases in the EBD group. The results revealed that there was a significant difference in the incidence rate of implantation metastasis between the PTBD group and EBD group (OR=0.35, 95% CI: 0.23-0.53, P<0.00001). Subgroup analysis revealed that the incidence rates of both catheter-related implantation metastasis and peritoneal metastasis were lower in the EBD group (OR=0.23, 95% CI: 0.12-0.44, P<0.00001; OR=0.47, 95% CI: 0.31-0.74, P=0.0008, respectively), and the advantage of EBD was demonstrated in perihilar cholangiocarcinoma, distal cholangiocarcinoma and pancreatic carcinoma (OR=0.35, 95% CI: 0.17-0.74, P=0.006; OR=0.32, 95% CI: 0.17-0.60, P=0.0005; OR=0.27, 95% CI: 0.19-0.40, P<0.00001, respectively). In conclusion, this meta-analysis revealed the appropriate choice of preoperative biliary drainage for resected MOJ. The application of EBD reduced the incidence rate of implantation metastasis, however more evidence is required from future studies, to confirm the results.
