Use of a curved needle to facilitate lateral sagittal infraclavicular block performance: a randomized clinical trial.
Trial report in Journal of anesthesia, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02799576 (A Curved Block Needle for the Infraclavicular Brachial Plexus Block in Patients Undergoing Surgery Distal to the Elbow), which is not on this 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.

Abstract
purposeFailed needle-tip positioning in an ultrasound-guided infraclavicular block can be due to improper needle insertion point and steep needle insertion angle. Needle pre-curving enables the user to pass the needle with different curved trajectories on approaching the brachial plexus. Aim of the study was to compare curved and non-curved needles as regards the time needed to perform the lateral sagittal infra-clavicular block.
methodsSixty-nine patients undergoing surgery distal to the elbow were randomly allocated to two groups: group A (n = 35), which received ultrasound-guided infraclavicular block using the curved needle; and group B (n = 34), which received the infraclavicular block using the non-curved needle. The primary outcome measure was the time needed to perform the infraclavicular block. Anesthetist's experience with the curved vs. non-curved needle was noted.
resultsMean (SD) recognition time (120 ± 48 vs. 179 ± 72 s, P = 0.0002) and injection time (54 ± 23 vs. 88 ± 36 s, P = 0.0001) were shorter in group A compared to group B. Median (IQR) procedure pain score was less in group A 2 (1-2) than in group B 2 (2-3); P = 0.001. Median (IQR) satisfaction score was higher with regards to the curved needle 4 (4-5) than non-curved needle 3 (3-4) in performing infraclavicular blockade; P = 0.001.
conclusionThe use of a curved needle reduces the time required to perform the lateral sagittal infraclavicular block. The curved needle provides less procedure pain and higher satisfaction levels among anesthetists than the non-curved needle.
