1 · What the graph read from 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.

2 · The registry

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

Immune checkpoint inhibitors (ICIs) have transformed cancer therapy by releasing inhibitory pathways that restrain antitumor T-cell responses. Their success has renewed interest in checkpoint blockade for infectious diseases, particularly chronic viral infections, sepsis-associated immunosuppression, and refractory opportunistic infections. In these settings, immune checkpoints may contribute to pathogen persistence by limiting effector function, but they also restrain tissue injury, cytokine excess, and immune-mediated organ damage. This dual role makes translation fundamentally different from oncology: the goal is not maximal immune activation, but controlled immune recalibration. Evidence is strongest for chronic viral infections and selected oncology-adjacent cohorts, whereas infection-directed trials remain early and heterogeneous. A precision framework based on pathogen burden, immune phenotype, tissue vulnerability, biomarker feasibility, safety monitoring, and implementation context is therefore essential before ICIs can be responsibly developed as host-directed therapies for infectious diseases. This review synthesizes the rationale, evidence, and safety considerations for ICIs in infectious diseases. We discuss chronic viral infections, including human immunodeficiency virus (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV), and Epstein-Barr virus (EBV), and highlight EBV as a bridge between persistent viral infection, immune surveillance, lymphoproliferation, and cancer immunotherapy. We also examine tuberculosis, sepsis, fungal infections, and parasitic diseases, where checkpoint pathways may restore host defense or amplify immunopathology. Finally, we propose a precision-immunotherapy framework integrating pathogen biology, immune phenotype, tissue risk, biomarker feasibility, access, and trial design.
