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
Purpose: To investigate the efficacy of intranasal esketamine in reducing the incidence of emergence agitation (EA) in pediatric patients undergoing adenotonsillectomy and to determine the optimal dose of esketamine. Methods: A total of 204 children aged 3-6 years scheduled for adenotonsillectomy were randomly assigned to three groups. All participants received a standardized anesthetic induction protocol. Following tracheal intubation, they were administered intranasally 0.5 mg/kg esketamine (group LE), 1 mg/kg esketamine (group HE), or an equivalent volume of saline (group C). Anesthesia was maintained with sevoflurane during surgery, and the children were transferred to the post-anesthesia care unit (PACU) after extubation. The highest scores on the Pediatric Anesthesia Emergence Delirium (PAED) scale and the modified Children's Hospital of Eastern Ontario Pain Scale (m-CHEOPS) in the PACU were recorded. The incidence of EA, defined as PAED ≥ 10, was calculated for each group. Additionally, changes in vital signs after intranasal administration, surgery time, anesthesia time, extubation time, eye-opening time, recovery time, and the incidence of adverse reactions were compared among the three groups. Results: Group LE demonstrated a significantly lower incidence of EA compared with group C (10.45% vs 29.85%, Conclusion: Intranasal esketamine at a dose of 0.5 mg/kg significantly reduces the incidence of EA following pediatric adenotonsillectomy. Increasing the dose to 1 mg/kg does not confer additional benefit in preventing EA and may instead delay extubation.
