The Thai version of the Nijmegen questionnaire.
Article in Heliyon, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled 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.
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: The Nijmegen questionnaire is a screening tool for detecting hyperventilation syndrome. The present study aimed to cross-culturally adapt the questionnaire to Thai language and test its psychometric properties for screening hyperventilation syndrome, in which the prevalence is increasing due to the impacts of the COVID-19 pandemic. Findings: The obtained IOC and disappeared floor and ceiling effects indicated excellent content validity of the questionnaire. There were significant correlations between the total scores of the NQ-TH and other questionnaires and recorded respiratory measurements obtained from the patients, i.e., SF-36-TH (
