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
This study aimed to develop and validate an instrument to assess Brazilian adults' knowledge, perceptions, and behaviors (KPB) toward salt and sodium. Based on a PAHO/WHO questionnaire, a new instrument was developed and evaluated by 11 experts, generating item and scale-level content validity indexes (I-CVI and S-CVI, respectively). Face validity was verified through a focus group with eight participants, followed by an operational test with 36 interviewees. Exploratory factor analysis (EFA) was used to determine the construct validity, and Cronbach's α coefficient was calculated to analyze instrument's reliability, using data collected via telephone from a probabilistic sample of 422 adults. The generated solutions were analyzed from theoretical and statistical significance perspectives, which supported the determination of the best model. Remaining items were scored, with higher scores related to healthier practices. A descriptive analysis was performed considering the data from the 422-adult sample. I-CVIs (0.73-1), S-CVIs (0.93; 0.97) and the interviewees' analysis indicated that items are representative and clear, in addition to being suitable for application to the target audience. Tests confirmed sample adequacy to perform the EFA (KMO = 0.82; Bartlett's sphericity test, p < .001). The final validated model, with 16 items, sufficiently explained the variance and presented good reliability (Cronbach's α = 0.81; 95% CI 0.79 - 0.84). Women, older individuals, and with higher education had significantly higher scores, regardless of chronic diseases diagnosis (p < .001). This instrument is ready to be applied and easily reproduced, contributing to the assessment of KPB toward salt and sodium in Brazil.
