Validity and reliability of the dietary sodium restriction questionnaire in patients with hypertension.
Article in European journal of clinical nutrition, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
The study aimed to evaluate the reliability and the validity of the dietary sodium restriction questionnaire (DSRQ) in patients with hypertension receiving outpatient treatment at a tertiary care university hospital in Southern Brazil. This instrument is composed of three subscales: attitude, subjective norm and perceived behavioral control. A total of 104 patients were included. They were 63.3±8.9 years old and 75% were females. Cronbach's alpha coefficient for the subscales of attitude, subjective norm and perceived behavioral control were 0.75, 0.37 and 0.82, respectively. The PCA with the extraction of three factors explained a total of 53.5% of the variance. The data suggest that the 15-item DSRQ is reliable and has internal consistency of its construct to measure the barriers and the attitudes of hypertensive patients related to dietary sodium restriction and may be useful to improve blood pressure control.
