A Comparative Analysis of the Quadratus Lumborum Block Versus Femoral Nerve and Fascia Iliaca Blocks in Hip Arthroscopy.
Article in Arthroscopy, sports medicine, and rehabilitation, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 14 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
purposeTo evaluate the effect of the single-shot quadratus lumborum (QL) block versus femoral nerve and fascia iliacus (F/FI) blocks performed preoperatively on perioperative opioid requirements, subjective pain scores, and time to discharge.
methodsPatients who underwent hip arthroscopy for femoroacetabular impingement and had a preoperative nerve block between January 2017 and August 2019 at our institution were identified. Patients were separated into 2 groups: those who either received a preoperative single-shot QL block or a preoperative single-shot F/FI block. All patients received general anesthesia. Intraoperative, postanesthesia care unit (PACU), and total morphine equivalents were analyzed using unpaired
resultsOne hundred one patients were retrospectively reviewed. Forty-three patients received preoperative QL blocks, and 58 patients received preoperative F/FI blocks. Demographics and operative characteristics were similar between the 2 groups. Patients receiving a QL block required significantly lower total morphine equivalents (63.1 vs 87.0,
conclusionsPatients receiving a preoperative QL block for hip arthroscopy demonstrated lower total opioid requirements, shorter PACU stay, and lower pain scores at discharge than patients receiving preoperative F/FI blocks with no reported adverse events. LEVEL OF EVIDENCE: Level III, retrospective comparative trial.
