Mediating role of health locus of control in supportive care needs and health promoting behaviours among patients with tuberculosis in China: a cross-sectional study.
Article in BMJ open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectivesTo explore the mediating role of health locus of control in the relationship between supportive care needs and health promoting behaviours among patients with pulmonary tuberculosis.
designA cross-sectional study.
settingThis survey was conducted in three tuberculosis-designated hospitals in Xi'an, China, between March and May 2020.
participantsA total of 294 participants completed the questionnaires. OUTCOME MEASURES: The participants completed a self-designed socio-demographic questionnaire, the Multidimensional Health Locus of Control scale, the Supportive Care Needs Scale for Patients with Tuberculosis and the Health Promoting Lifestyle Profile II. SPSS V.26.0 and Mplus were used for data analysis.
resultsThe patients' supportive care needs had a negative association with their health promoting behaviours (r=-0.58, p<0.001). The supportive care needs were negatively related to internal health locus of control (r=-0.43, p<0.001), and positively related to chance health locus of control (r=0.44, p<0.001) and powerful others health locus of control (r=0.20, p<0.001). Health-promoting behaviours had a significantly positive correlation with internal health locus of control (r=0.49, p<0.001) and a negative correlation with chance health locus of control (r=-0.36, p<0.001). Both internal health locus of control and chance health locus of control acted as mediators between supportive care needs and health promoting behaviours, while powerful others health locus of control did not.
conclusionHealth locus of control mediated the relationship between supportive care needs and health promoting behaviours. A high level of internal health locus of control and a low level of chance health locus of control may help to improve health-promoting behaviours. Given the cross-sectional design of this study, future experimental interventions targeting health locus of control are needed to establish causal relationships with supportive care needs and health promoting behaviours.
