Comparison of short-axis and oblique-axis approaches for ultrasound-guided right internal jugular vein cannulation in the left decubitus position: a randomized clinical trial study protocol.
Article in Trials, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundThe internal jugular vein (IJV) cannulation in the decubitus position is required in some urgent and special clinical situations, increasing the difficulty of performance. Although ultrasound guidance can improve the efficiency and safety of IJV cannulation, ultrasound guidance for right internal jugular vein (RIJV) cannulation in the decubitus position has not been studied. This trial aims to compare the feasibility and safety of an ultrasound-guided oblique-axis approach with a short-axis approach for left decubitus RIJV cannulation.
methodsA total of 74 patients undergoing IJV cannulation in the left decubitus position under general anesthesia will be randomly divided into two groups: the oblique-axis group (OA group) and the short-axis group (SA group). In both groups, the surgical bed will be rotated 20° to the Trendelenburg position prior to puncture to allow for better filling of the RIJV for catheterization. The primary endpoint is the first-time puncture rate. Secondary endpoints include overall catheterization success rate, overall catheterization time, number of venipuncture attempts, and incidence of mechanical complications. DISCUSSION: We hypothesize that the feasibility and safety of the ultrasound-guided oblique-axis approach for RIJV cannulation will be superior to those of the short-axis approach in the left decubitus position. Our findings may provide a clinical preference for central venous cannulation in certain position for surgical patients. CLINICAL
