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
backgroundEffective prehospital care for acute chest pain critically relies on ambulance nurses' adherence to clinical guidelines. However, current adherence is inadequate, with no instruments available to improve the situation. Therefore, this study aimed to develop and psychometrically evaluate an instrument measuring ambulance nurses' adherence to and attitudes towards acute chest pain guidelines, and to adapt and test the Attitudes Regarding Practice Guidelines instrument for measuring general attitudes towards guidelines.
methodsAn instrument development design was used. A 49-item Adherence Instrument was initially developed for measuring adherence to and attitudes towards acute chest pain guidelines and the 18-item Attitudes Regarding Practice Guidelines instrument was translated into Swedish. Both instruments were validated through cognitive interviews and expert reviews. To ascertain its reliability, a test‒retest was conducted. The construct validity of the Adherence Instrument was assessed via principal component analysis on the basis of a polychoric correlation matrix.
resultsThe developed Adherence Instrument was refined to 18 items and showed strong validity and reliability. Similarly, the Attitudes Regarding Practice Guidelines instrument, refined to 12 items, demonstrated strong validity and reliability. Principal component analysis of the Adherence Instrument identified five components: professional evidence-based practice, assessment of symptoms, confidence in skills, clinical autonomy, and guideline clarity and education. These components accounted for 64.5% of the total variance and demonstrated strong reliability, with an ordinal alpha of 0.84 for the entire scale.
conclusionThe psychometric properties of the Adherence Instrument were satisfactory and will be useful in prehospital emergency care to measure attitudes and adherence towards acute chest pain guidelines.
