Effects of Brief Adjunctive Metformin Therapy in Virologically Suppressed HIV-Infected Adults on Polyfunctional HIV-Specific CD8 T Cell Responses to PD-L1 Blockade.
Trial report in AIDS research and human retroviruses, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers, 1 of them a synthesis that pooled it.
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
Targeting inhibitory immune checkpoint receptor pathways has shown remarkable success in improving anticancer T cell responses for the elimination of tumors. Such immunotherapeutic strategies are being pursued for HIV remission. Metformin has shown favorable clinical outcomes in enhancing the efficacy of programmed cell death-1 (PD-1) blockade and restoring antitumor T cell immunity. Furthermore, monocytes are known to be a strong predictor of progression-free survival in response to anti-PD-1 immunotherapy. In a single-arm clinical trial, we evaluated the immunological effects over an 8-week course of metformin therapy in seven euglycemic, virally suppressed HIV-infected participants on combination antiretroviral therapy (cART). We assessed changes in peripheral HIV-Gag-specific T cell responses to immune checkpoint blockade (ICB) with anti-PD-L1 and anti-T cell immunoreceptor with immunoglobulin and ITIM domain (TIGIT) monoclonal antibodies (mAbs) and changes in CD8 T cell and monocyte subsets using flow cytometry. Study participants were all male, 71% (5/7) Caucasian, with a median age of 61 years, CD4 count of 739 cells/μL, and plasma HIV RNA of <50 copies/mL on stable cART for >1 year.
