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 determine the safety and efficacy of percutaneous intraductal radiofrequency ablation (RFA) combined with biliary metal stent placement for patients with unresectable malignant biliary obstruction.

methodsFrom a cohort of 70 patients with unresectable malignant biliary obstruction, 28 patients received percutaneous intraductal RFA combined with biliary stent placement (group A) and the remaining 42 were treated with biliary metal stent placement only (group B). Stent patency, overall survival (OS), alleviation of jaundice, and postoperative complications were assessed.

resultsThe technical success rate for both groups was 100%. No severe complications (e.g., biliary bleeding, perforation) occurred. In both groups, jaundice was relieved and the decrease of the total and direct bilirubin concentration was significant (p < 0.01). The median time of stent patency in group A and group B were 6.6 ± 0.3 months (95% CI 6.1-7.1 months) and 4.9 ± 0.4 months (95% CI 4.2-5.6 months), respectively (p < 0.01). The median overall survival times in Group A were 7.2 ± 0.3 months (95% CI 6.5-7.9 months) versus 5.6 ± 0.4 months (95% CI 4.8-6.4 months) in group B (p < 0.01). In univariate and multivariate analyses, intraductal RFA, stent patency, and decreased baseline serum direct bilirubin concentration were associated with greater OS (p < 0.05).

conclusionPercutaneous intraductal RFA combined with stent placement is a safe and effective method for patients with malignant biliary obstruction. As compared to stent placement alone, percutaneous intraductal RFA can significantly prolong stent patency and improve the overall survival of patients with malignant biliary obstruction.
