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 describe a novel technique of percutaneous transhepatic (PTH) placement of a plastic biliary stent (PBS), report the feasibility and safety of the technique, and present the preliminary results of a pilot study that included 32 patients with symptomatic obstructive jaundice (SOJ) treated with the technique. MATERIALS AND

methodsThis was a prospective, single-arm, single-center, pilot study of a cohort of patients with the diagnosis of benign or malignant obstructive jaundice that underwent PTH placement of a PBS to relieve the obstruction.

resultsThirty-two patients were included, 16 men and 16 women (age range, 35-88 years). There were 26 malignant and six benign lesions. Cholangiocarcinoma was the most common tumor (n=13, 40.6%), followed by pancreatic adenocarcinoma (n=6, 18.75%) and metastasis (n=5, 15.6%). A total of 35 PBSs were placed in 32 procedures. The bile duct was accessed and drained to the right side in 18 cases, to the left side in 14 cases, and bilaterally in three cases. Technical success was achieved in 100% and clinical success in 93.7% of cases. Using a modified Bismuth-Cortelle classification system, type I was observed in nine patients, type II in nine patients, type III in six patients, and type IV in eight patients. The mean follow-up was 426.1 days for the total sample, and 349.4 days for patients with malignancy. Two complications were observed: transient hemobilia and cholangitis.

conclusionPTH placement of a PBS in patients with SOJ is feasible, safe, and effective.
