Testing the Interpersonal-Behavior model to explain intentions to use patient-delivered partner therapy.
Article in PloS one, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04865341 (Optimizing an IMB-guided Intervention to Support HIV Self-testing and PrEP Uptake Among YMSM), which is not on this 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.

Abstract
backgroundPatient-delivered partner therapy (PDPT) is an evidence-based method of partner treatment, but further research was needed to understand theoretical underpinnings of potential PDPT use. PURPOSE: We sought to develop and test a theoretical framework to understand PDPT intentions.
methodsA Midwestern sample of sexually transmitted infection clinic patients were recruited to participate in a three-phase study incorporating semi-structured interviews (n = 20, total), cognitive interviews (n = 5), and surveys (n = 197; Mage = 31.3, 61% male, 91% Black or African-American). Thematic analysis was conducted to identify major themes, which guided development and testing of a theoretical framework on PDPT intentions using structural equation modeling.
resultsWe identified themes of information (knowledge); motivation (individual and partner protection beliefs, partner and provider motivation-to-comply); social support (sexual health and general); and behavioral skills (partner notification, medication delivery, and communication skills self-efficacy) in thematic analysis. The developed Interpersonal-Behavior model demonstrated good model fit in structural equation modeling [χ2(36) = 95.56, p<0.01; RMSEA = 0.09 (0.07-0.11, 90%C.I.); CFI = 0.94; SRMR = 0.05]. Information was associated with motivation (β = 0.37, p<0.001) and social support (β = 0.23, p = 0.002). Motivation was associated with social support (β = 0.64, p<0.001) and behavioral skills (β = 0.40, p<0.001), and social support was associated with behavioral skills (β = 0.23, p = 0.025). Behavioral skills were associated with higher PDPT intentions (β = 0.31, p<0.001), partially mediated the association of motivation with intentions (βdirect = 0.53, p<0.001; βindirect = 0.12, 95%CI: 0.03-0.30), and fully mediated the association of social support with intentions (βindirect = 0.07, 95%CI: 0.00-0.21).
conclusionsThe Interpersonal-Behavior model seems appropriate for PDPT intentions but should be tested longitudinally with PDPT outcomes and other interpersonal health behaviors.
