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

Background: Chimeric antigen receptor (CAR) T-cell therapy has shown limited efficacy against solid tumors due to antigen heterogeneity and scarcity of tumor-specific targets. Methods: To address those challenges, we report a covalent CAR-T strategy that achieves programmable tumor recognition via oncolytic adenovirus-mediated (OAD) delivery of artificial antigens. An engineered OAD was designed to induce tumor-selective expression of a membrane-anchored SpyTag-containing artificial antigen on infected tumor cells. In parallel, we generated SpyCatcher CAR-T cells by replacing the conventional single-chain variable fragment (scFv) with SpyCatcher, which forms a spontaneous covalent bond with SpyTag and redirects CAR-T-cell activity toward virus-labeled tumor cells. Results: Conclusions: This study establishes a modular platform for solid tumor immunotherapy therapy by integrating covalent SpyCatcher CAR-T cells with SpyTag-delivering OAD. By decoupling tumor recognition from endogenous antigen expression, this approach provides a generalizable strategy to overcome antigen heterogeneity and scarcity of tumor-specific targets in solid tumors.
