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
Combined intraperitoneal and incisional block provides effective perioperative analgesia but is limited in clinical practice. Intravenous lidocaine offers an alternative, although its analgesic efficacy remains controversial. This study compared the postoperative analgesic efficacy of lidocaine intravenous infusion with combined intraperitoneal and incisional lidocaine splash in dogs undergoing ovariohysterectomy. Thirty female dogs were randomized to intravenous infusion (IV), intraperitoneal and incisional splash (IP + SP), or control (C). Anesthesia included intramuscular acepromazine (0.03 mg/kg), intravenous propofol (4-6 mg/kg), isoflurane maintenance, and fentanyl (2 µg/kg) intravenous pre-incision. Group IV received intravenous lidocaine 2 mg/kg and then 50 μg/kg/min infusion. Group IP + SP received lidocaine 4 mg/kg intraperitoneally intraoperatively and 2 mg/kg as an incisional splash before skin closure. Controls received saline. Postoperative pain was assessed using the Glasgow Composite Measure Pain Scale-Short Form and analyzed using a linear mixed model. At 60 min, pain scores were 1.2 ± 0.4 (IP + SP), 1.6 ± 0.7 (IV), and 3.0 ± 2.8 (C) and at 120 min 1.3 ± 0.5, 1.4 ± 0.7, and 2.3 ± 0.8, respectively. Both treatments had significantly lower scores than controls (
