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.

Abstract
backgroundPediatric circumcision is a common yet often distressing procedure due to the associated pain and emotional response it can elicit in children. Adequate sedation and analgesia are critical to mitigate these effects and ensure the procedure's success. The combination of propofol and opioids continues to be the most commonly utilized intravenous anesthetic regimen for pediatric circumcision procedures. However, due to its narrow therapeutic index, propofol may cause notable hemodynamic and respiratory depression. Esketamine, an S(+)-isomer of ketamine, is recognized for its analgesic potency and minimal respiratory impact. Furthermore, its sympathomimetic properties offer a counterbalance to the hemodynamic inhibition of propofol. Therefore, the aim of this study is to determine the optimal dose of esketamine combined with propofol for pediatric circumcision.
methodsThis prospective, randomized controlled, dose-finding clinical trial will enroll 100 children aged 3-9 years who undergo circumcision. Participants will be randomly assigned to five groups to receive varying doses of esketamine (0.50, 0.75, 1.00, 1.25, and 1.50 mg/kg) combined with 3 mg/kg propofol for achieving adequate sedation. An effective dose of esketamine will be defined as non-occurrence of physical movement, frowning, or Ramsay Sedation Scale (RSS) score ≥ 5 during skin incision. The values for median effective dose (ED DISCUSSION: The results of this study seek to determine the ED
