Transmuscular quadratus lumborum block for postoperative pain and recovery after laparoscopic adrenalectomy: a randomized controlled trial.
Trial report in BMC anesthesiology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03942237 (Transmuscular Quadratus Lumborum Block for Postoperative Pain After Laparoscopic Adrenalectomy), which is not on this map. Cited by 5 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
backgroundTo investigate the role of transmuscular quadratus lumborum block (TMQLB) for postoperative pain control, patient satisfaction and recovery in laparoscopic adrenalectomy.
methodsSeventy-two patients aged between 18 and 70 years with an ASA I-II and scheduled for laparoscopic adrenalectomy were randomized to receive a single-shot TMQLB with 0.4 ml/kg 0.5 % ropivacaine or 0.4 ml/kg 0.9 % saline as placebo. The primary endpoint was pain on movement at 12 h after surgery evaluated by the numeric rating scale (NRS, 0-10). P-values < 0.05 was considered statistically significant. The secondary outcomes included pain at rest and pain on movement evaluated by the NRS, and postoperative recovery related parameters.
resultsNRS on movement at 12 h after surgery was lower in the TMQLB group compared with the control (median 2 vs. 3, p = 0.024). Intraoperative fentanyl consumption was lower in the TMQLB group (247.08 ± 63.54 vs. 285.44 ± 74.70, p = 0.022). The rate of using postoperative rescue tramadol was also lower in the TMQLB group (5.6 vs. 27.8 %, p = 0.027). Similar incidences of nausea and vomiting were observed (11.1 vs. 25 %, p = 0.220). Patient satisfaction of pain service was better in the TMQLB group (83.3 vs. 25 %, p < 0.001) with shorter time to ambulation (16.5 vs. 21 h, p = 0.004) and flatus (18.5 vs. 23.5 h, p = 0.006).
conclusionsTMQLB showed better control of postoperative pain on movement for laparoscopic adrenalectomy with improved patients' satisfaction of anesthesia, shorter time to ambulation and flatus.
