Scrubbing needles: a simple and costless technique to improve needle tip visibility during US-guided liver interventions.
Trial report in Journal of ultrasound, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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.
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
aimsTo evaluate the echogenicity of a commercially available needle, modified on the tip, by comparing two groups of patients undergoing to percutaneous biliary drainage.
methodsIn this retrospective analysis 16 percutaneous transhepatic biliary drainage (PTBD) procedures performed on 16 oncologic patients were evaluated. Patients were randomly divided into two groups of eight subjects each; in the first group, a standard needle was adopted (group A); in the second group, the needle was manually modified to create a rough surface (group B), by scrubbing the tip with an 11 scalpel blade for 150 s all around its surface. To objectively quantify US needle tip visibility, the contrast-to-noise ratio (CNR) was calculated analyzing B-mode images by positioning region of interests in correspondence of needle tip and liver parenchyma.
resultsNeedle tip echogenicity was significantly higher in group B where the needle tip was modified compared to control group A (p value = 0.014). CNR, considered to objectively evaluate differences among needle tip echogenicity, was significantly higher in group B with respect to control group A (p value = 0.018).
conclusionsThe proposed method, scrubbing a 22 gauge commercially available needle tip with a scalpel blade, represents an effective technique to improve needle visibility during US-guided punctures of the liver.
