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
Aim: To evaluate the anxiolytic, amnesic, physiological, and psychomotor effects of nitrous oxide (N2O) inhalation sedation in children indicated for dental treatment. Methods: A total of 44 children indicated for single-sitting pulpectomy were divided into group I (control group) and group II (single-sitting pulpectomy under nitrous oxide inhalation sedation) to evaluate anxiolytic, amnesic, physiological, and psychomotor effects of nitrous oxide inhalation sedation. Physiological, anxiolytic, psychomotor, and amnesic effects were assessed using pulse oximeter, Modified Dental Anxiety Scale (MDAS), salivary cortisol levels, salivary nitric oxide (NO) levels, Bender visual motor Gestalt test, and recalling of images of shapes, respectively. Results: The results revealed statistically significant difference in pulse rate (PR) intraoperatively under nitrous oxide sedation but no significant difference in oxygen saturation (SpO₂) among the groups. Anxiety had significantly reduced after onset of sedation due to the anxiolytic effect of N₂O. Significant impairment of coordination and psychomotor ability was seen intraoperatively under nitrous oxide sedation. Statistically significant levels of amnesia were observed in nitrous oxide inhalation sedation. Conclusion: Nitrous oxide sedation caused a significant decrease in anxiety, a significant effect on amnesic and psychomotor abilities of children.
