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

Near-infrared photoimmunotherapy (NIR-PIT), a newly developed cancer-cell-specific therapy, relies on a monoclonal antibody-photoabsorber conjugate (APC) and is based on a photoinduced ligand release reaction. Local exposure of the tumor to NIR light induces rapid immunogenic necrotic cell death. The molecular properties of APCs, including their stability and aggregation properties, have important implications for the long-term stability and shelf life. In this study, panitumumab was conjugated with IRDye700DX (IR700) as a model for other NIR-PIT agents. Higher IR700-to-mAb conjugation ratios correlated with increased in vitro cell death up to a ratio of 2.5 dye molecules per antibody. Conjugation ratios higher than 2.5 did not improve cell killing activity. APC aggregation was induced in a light-dose-dependent manner. A near-room-level light dose was sufficient to induce aggregation of APCs. Solvent pH lower than 4 induced aggregation, but higher pH did not induce aggregation. The IR700-to-mAb conjugation ratio, light irradiation dose, and solvent pH affect the APC stability and efficacy.
