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
ObjectivesThe aim of the present study was to compare analgesic and cardiopulmonary effects after bilateral ultrasound-guided quadratus lumborum block (QLB) and lumbosacral epidural (LsE) with levobupivacaine in cats undergoing ovariohysterectomy (OVH).MethodsA prospective, randomized, blinded clinical trial was conducted. A total of 20 healthy female cats were allocated (1:1) to the LsE group (0.4 ml/kg 0.25% levobupivacaine) or the QLB group (0.3 ml/kg 0.25% levobupivacaine per hemiabdomen). Cats were premedicated with dexmedetomidine 3 µg/kg and meloxicam 0.1 mg/kg. Anesthesia was performed using propofol variable rate infusion (adjusted to clinical depth). Heart rate, respiratory rate, hemoglobin oxygen saturation, end-tidal carbon dioxide and systolic, mean and diastolic arterial pressures were recorded at seven standardized surgical time points. Postoperative pain (UNESP-Botucatu multidimensional composite pain scale) and sedation were assessed up to 6 h after surgery; methadone (0.25 mg/kg IM) was administered as rescue analgesia when indicated. Recovery milestones and mean propofol infusion rates were also compared. Data were analyzed using repeated measures ANOVA, unpaired
