The influencing factors of phosphate control behavior among patients undergoing hemodialysis: based on the health belief model.

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
purposeImproving the adherence to phosphate management is crucial for reducing the incidence of mortality and complications and improving quality of life for patients undergoing hemodialysis. This study aimed to investigate the factors related to the phosphate control behavior and explore how the Health Belief Model constructs mediating the influence of phosphate-related knowledge on behavior in hemodialysis patients.
methodsIt was a multicenter cross-sectional study; 333 patients undergoing maintenance hemodialysis were recruited from 3 hemodialysis units of Peking University Third Hospital. Questionnaires were used to examine the phosphate management-related knowledge, health belief and behavior. Hierarchical multiple regression analysis was used to identify independent factors associated with phosphate control behavior. Parallel mediation model was used to test perceived threat, benefit, barrier, self-efficacy as potential mediators between phosphate knowledge and behavior.
resultsThe adherence of phosphate restriction diet got the lowest score (3.56 ± 0.88). Hierarchical multiple regression analysis showed that health belief explained 17.0% of the variance in phosphate control behavior. Parallel mediation analysis showed that the direct effect of knowledge on behavior was statistically significant (β = 0.19, SE= 0.05). Perceived threat (β = 0.07,
conclusionPerceived threat and self-efficacy mediated the effect of knowledge on phosphate control behavior, while perceived barrier influenced the behavior independently. HBM might be effective at developing phosphate control behavior change interventions.
