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
Background: The neutrophil-to-lymphocyte ratio (NLR) is one of the prognostic factors reflecting the balance between systemic inflammation and immunity in the body. This study aimed to compare the impact of laryngoscopy on hemodynamic status and NLR after induction of anesthesia with etomidate, propofol, and ketamine. Materials and Methods: This triple-blind, prospective clinical trial was conducted in 2022 on 90 laryngoscopy candidates. The patients were assigned to three groups of 30. For anesthesia, 0.3 mg/kg of etomidate in the first group, 2.5 mg/kg propofol in the second group, and 2 mg/kg of ketamine in the third group were injected slowly, and the patient underwent ventilation with 100% oxygen for at least 3 minutes; then, laryngoscopy, followed by intubation, was carried out. Blood samples were collected before intubation, immediately after recovery, 20 minutes later, 1 hour later, and at the end of recovery and transmitted to the laboratory. Results: Changes in systolic blood pressure ( Conclusion: The present study indicated that etomidate had hemodynamic stability and reduced changes in the mean values of lymphocyte, neutrophil, and NLR compared to ketamine and propofol.
