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
Background: No recommendations have been made regarding the puncture position during tunnelled dialysis catheter (TDC) insertion from right internal jugular vein (RIJV). We investigated the effect of puncture positioning along with other characteristics and clinical factors associated with TDCs to determine their correlation with catheter patency rate. Methods: We retrospectively reviewed TDC insertion procedures performed between January 2018 and December 2020 at a single institution. Patients were monitored for at least 1 year or until TDC removal or replacement. The distance on the post-operative chest radiography were measured to determine the height of puncture position. End points were freedom from catheter dysfunction. Results: Total 949 catheters met the eligibility criteria. Catheter dysfunction occurred in 233 patients and catheter infection in 127 patients. By multivariate analysis, female sex [hazard ratio (HR) =1.497, 95% confidence interval (CI): 1.119-2.002; P=0.007] and split-tip catheter (HR =1.453, 95% CI: 1.087-1.944; P=0.012) were associated with an increased rate of catheter dysfunction. Every 10-year increment in age (HR =1.243, 95% CI: 1.123-1.376; P<0.001) and every 1-cm increase in the height of the catheter insertion site (HR =1.270, 95% CI: 1.096-1.473; P=0.001) were also associated with an increased rate of catheter dysfunction. After classifying the height of puncture position into 3 groups, significant worse patency was observed in the catheter with puncture height more than 4 cm (P=0.025). No immediate complications were observed. Conclusions: TDC insertion at a high puncture site correlates with an increased risk of catheter dysfunction. Puncturing the RIJV close to the clavicle is safe and enhances catheter patency.
