Comparison between the long-axis in-plane and short-axis out-of-plane approaches for ultrasound-guided arterial cannulation: a meta-analysis and systematic review.

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 two most common methods for ultrasound-guided arterial cannulation are the long-axis in-plane (LA-IP) and short-axis out-of-plane (SA-OOP) approaches. However, it is uncertain which method is more advantageous. We conducted a meta-analysis of reported randomized clinical trials (RCTs) comparing the two techniques in terms of success rate, cannulation time, and complications.
methodsWe systematically searched PubMed, Embase, and the Cochrane Library database for RCTs comparing the LA-IP and SA-OOP techniques for ultrasound-guided arterial cannulation published from inception through April 31, 2022. The Cochrane Collaboration's Risk of Bias Tool was used to evaluate the methodological quality of each RCT. Review Manager 5.4 and Stata/SE 17.0 were used to analyze the two primary outcome measures (first-attempt success rate and total success rate) and two secondary outcome measures (cannulation time and complications).
resultsA total of 13 RCTs with 1,377 patients were included. There were no significant differences in first-attempt success rate (risk ratio [RR], 0.93; 95% confidence interval [CI], 0.78-1.12; P = 0.45; I
conclusionsThe present results suggest that the SA-OOP technique is associated with a higher incidence of posterior wall puncture and hematoma than the LA-IP technique, whereas success rates are similar for the two ultrasound-guided arterial cannulation techniques. These findings should be experimentally evaluated in a more rigorous manner due to high inter-RCT heterogeneity.
