Needle Direction and Distance of Arteriovenous Fistula Cannulation in Hemodialysis Adequacy; a Systematic Review and Meta-Analysis.
Review in Archives of academic emergency medicine, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Introduction: This systematic review and meta-analysis aimed to summarize the evidence regarding the impact of needle direction and distance of arteriovenous fistula (AVF) cannulation on KT/V (where k is the dialyzer urea clearance, t, the duration of dialysis, and V, the volume of distribution of urea) and access recirculation (AR) as hemodialysis (HD) adequacy criteria. Methods: A comprehensive systematic search was performed on international and domestic electronic databases from the earliest to June 4, 2022 using keywords. Analysis was performed in STATA software v.14. Results: Three randomized control trials (RCTs) and four non-RCT articles were included in the final review. Six studies reported the effects of direction, while four mentioned the effects of distances of AVF cannulation on outcomes of HD adequacy based on KT/V or AR. Results of three non-RCT studies showed that retrograde direction decreased KT/V more than antegrade direction (ES: 0.44, 95% CI: -0.38 to 1.27). Two non-RCT studies showed that antegrade decreased AR compared to the retrograde direction (ES: -0.64, 95%CI: -1.94 to 0.67). However, the results of two RCTs indicated uncertainty about this issue. Two of the four studies suggested that a distance of 5 cm or more in arterial and venous needles had greater adequacy than a distance of less than 5 cm. However, other studies did not confirm this finding. Conclusion: Overall comparison of the results qualitatively and quantitatively indicated uncertainty about the effects of direction and distance of AVF cannulation on HD adequacy outcomes. More studies with high-quality designs, such as RCTs, are required to better understand and adjudicate the effects of needle direction and distance of AVF cannulation on HD adequacy outcomes.
