Specific depletion of TIGIT
Article in Journal for immunotherapy of cancer, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundGlobal clinical programs based on TIGIT (T cell immunoglobulin and ITIM domain) blockade have been terminated due to inadequate clinical efficacy. New approaches are needed to increase the antitumor activity of anti-TIGIT-based immunotherapy.
methodsMultiomics analyses, including single-cell RNA sequencing (scRNA-seq), single-cell TCR sequencing (scTCR-seq), and The Cancer Genome Atlas bulk RNA-seq, were performed to profile TIGIT and the costimulator CD226 expression and assess intratumoral regulatory T cells (Tregs) clonality, with validation by flow cytometry in murine and patient-derived tumor-infiltrating lymphocytes. The therapeutic efficacy of anti-TIGIT antibodies (αTIGIT), including αTIGIT-IgG1-wild-type (WT), αTIGIT-IgG1-WT with enhanced antibody-dependent cellular cytotoxicity (ADCC) activity (αTIGIT-IgG1-ADCC), αTIGIT-IgG4-WT, and tiragolumab, was evaluated in MC38 tumors-inoculated humanized
resultsUsing mouse models and clinical sample analysis, we identified a population of TIGIT
conclusionsTargeted elimination of clonally expanded intratumoral Tregs is essential to unlock the full therapeutic potential of αTIGIT. These novel findings provide a key rationale and strategic direction for overcoming the limitations of current αTIGIT-based cancer immunotherapy.
