1 · What the graph read from it

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.

2 · The registry

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

purposeTo investigate the effectiveness and predictive factors of nitrous oxide and oxygen inhalation sedation (NOIS) in Thai paediatric dental patients.

methodsA retrospective chart review of children receiving dental treatments under NOIS between March 2022 and August 2024 was conducted. A sedation session was evaluated as effective when the Overall Houpt Behaviour Rating Scale was greater than or equal to 4 and there were no acute adverse events from NOIS during or within 24 h of sedation. Predictive factors were assessed using the Poisson regression with robust error variance and generalised estimating equations.

resultsA total of 224 sedation sessions from 134 Thai patients aged 3-12 years were included. Of these sessions, 86.2% were considered effective. In the multivariable analysis, previous NOIS experience and the child's preoperative anxiety level were associated with the effectiveness of NOIS. The risk ratio for effective sedation was 13% higher for children with prior NOIS experience compared to those undergoing NOIS for the first time (RR: 1.13, 95% CI 1.02-1.25, p value < 0.05). In addition, the risk ratio for effective sedation in non-anxious children was 41% higher than for extremely anxious children (RR: 1.41, 95% CI 1.07-1.86, p value < 0.05).

conclusionNOIS is safe and effective for dental treatment in Thai children, with minimal adverse events. Its effectiveness is particularly pronounced in children who have prior experience with NOIS and present as non-anxious.
