Comparison of types 2 and 3 quadratus lumborum muscle blocks : Open inguinal hernia surgery in patients with spinal anesthesia.
Article in Der Anaesthesist, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveThe efficacy of quadratus lumborum muscle block (QLB) in abdominal surgery is known; however, the efficacy of different QLB types is unclear. The objective of this study was to investigate the effects of ultrasound-guided QLB type 2 and type 3 on postoperative opioid consumption and pain scores in patients undergoing inguinal hernia surgery. MATERIAL AND
methodsIn this study 60 patients undergoing open inguinal hernia surgery were randomly assigned to 3 groups. Group QLB2 received ultrasound-guided QLB type 2 and group QLB3 received ultrasound-guided QLB type 3 with 0.25% 20 mL bupivacaine. In the control group (group C) no intervention was performed. Postoperative analgesia was performed intravenously with 1000 mg paracetamol every 6 h and patient-controlled analgesia with fentanyl. Postoperative visual analog scale scores (VAS), opioid consumption, and first analgesic requirement time were evaluated.
resultsFentanyl consumption was significantly higher in group C compared to the other groups at all time intervals (p < 0.05). Fentanyl consumption was significantly higher in group QLB2 compared to QLB3 at the 4-8 h, 8-24 h, and total 24 h. Passive VAS 4h and 8 h, active VAS 4h, 8h, and 12 h were significantly lower in group QLB3 compared to QLB2 (p < 0.05). The first analgesic time was significantly later in group QLB2 compared to group C (280.52 ± 89.20 min and 183.75 ± 42.79 min, respectively) and even later in group QLB3 compared to the other two groups (463.42 ± 142.43 min, p < 0.05).
conclusionThe use of QLB2 and QLB3 decreased postoperative opioid consumption and pain scores in patients undergoing inguinal hernia surgery. Furthermore, QLB3 provided more effective and longer lasting postoperative analgesia and lower opioid consumption compared to QLB2.
