Effect of ultrasound-guided pericapsular nerve group (PENG) block on pain during patient positioning for central nervous blockade in hip surgery: a randomized controlled trial.
Trial report in BMC anesthesiology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to 3 registered trials, which are not on this map. Cited by 8 papers, 1 of them a synthesis that pooled it.
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.

Abstract
backgroundMost patients with hip fractures are elderly patients with comorbidities, and well-managed pain management is associated with positive postoperative outcomes. In recent years, new indications for regional anesthesia techniques have been defined, and they have found more place in clinical practice. Herein we investigate the effect of US-guided PENG block on positioning pain and compare that effect to intravenous opioid in patients undergoing surgery under spinal anesthesia for hip fractures. Additionally, we sought to investigate the effect of PENG block on pain scores, opioid intake, time to first analgesic requirement, and quality of recovery within the first 24 h following surgery.
methodsIn this study, patients were divided into the PENG (n = 42) and control group (n = 42) one hour prior to surgery. A team who was blinded to the assigned groups, collected and evaluated all data such as spinal anesthesia positioning pain, postoperative pain, opioid requirement.
resultsPatients that underwent PENG had statistically significantly lower NRS scores after interventions, immediately before positioning, at positioning and at end of spinal anesthesia. Pain scores during positioning for spinal anesthesia were statistically significantly lower in the PENG group than in the control group (p < 0.001). Total morphine use over the first 24 h was extremely statistically significantly lower in the PENG group (p < 0.001).
conclusionsPositive outcomes of PENG block in patient positioning pain before spinal anesthesia, postoperative pain scores, and morphine consumption are consistent with similar studies. High patient satisfaction in patients who underwent PENG block contributes to the literature.
