The analgesic efficacy of quadratus lumborum block in caesarean delivery: a meta-analysis and trial sequential analysis.
Synthesis in Journal of anesthesia, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
purposeQuadratus lumborum block (QLB) has recently gained popularity for postoperative analgesia after cesarean delivery (CD) as it provides both visceral and somato-sensory blockade of the abdomen. Aim of this meta-analysis was to evaluate the analgesic potential of QLB after CD.
methodsElectronic database from inception to December 2019 was searched systematically for randomized-controlled trials comparing QLB with injection of inactive solution in women undergoing CD. Primary outcome was consumption of morphine at 24 h. Morphine consumption at 48 h, dynamic and static pain scores at various time intervals were the secondary outcomes studied.
resultsSeven trials met the inclusion criteria. Morphine consumption was reduced significantly with QLB in comparison to sham or no block at 24 h (mean difference [MD] - 9.84 mg; 95% confidence interval [CI] - 18.16, - 0.50; p = 0.04; I
conclusionQLB significantly reduces opioid requirements in CD and may have analgesic effects lasting 24 h.
