Optimizing HIV Partner Services for Gay, Bisexual, and Other Men Who Have Sex With Men Previously Diagnosed With HIV: A Modeling Study.

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
backgroundHIV Partner Services (HIV-PS) is a vital strategy for identifying and linking individuals to treatment and prevention; however, its population-level impact has been limited. This study investigated the potential impact of expanding HIV-PS to include previously diagnosed individuals and a broader sexual partner network in reducing HIV incidence among gay, bisexual, and other men who have sex with men (GBMSM).
methodsStochastic network models were used to simulate HIV and bacterial sexually transmitted infection transmission within male same-sex partnerships in Atlanta. Two primary interventions were examined: prioritizing people with previously diagnosed HIV who were out-of-care (PWDH-OOC) in routine HIV-PS and expanding partner elicitation to include partners of HIV-positive partners of index cases. We quantified how modifications to HIV-PS cascade steps under these interventions would impact HIV incidence among GBMSM.
resultsExpanded partner elicitation modestly increased the pool of partners eligible for linkage to transmission-disrupting services, with minimal impact on HIV incidence. In contrast, including PWDH-OOC led to a 10-fold increase in both index-case and partner pools. However, substantial reductions in HIV incidence required enhancements to other HIV-PS steps, particularly in partner identification and antiretroviral therapy (ART) reengagement for PWDH-OOC. Prioritizing ART reengagement for PWDH-OOC, alongside optimized HIV-PS, resulted in up to 63% of HIV infections being averted.
conclusionsOur study highlights the potential of strategic improvements to HIV-PS for accelerating HIV incidence reduction among GBMSM. Synergistic optimization of HIV-PS, along with prioritizing ART reengagement for previously diagnosed individuals, will be essential for achieving substantial reductions in HIV incidence.
