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

The clinical development of 4-1BB agonists for cancer immunotherapy has been constrained by dose-limiting toxicities, particularly hepatotoxicity. To overcome this challenge, we developed FTL008.16, a novel bispecific antibody targeting 4-1BB (CD137) on T cells and the tumor-associated antigen 5T4. FTL008.16 is a human IgG1 antibody bearing an effector-deficient Fc region that specifically binds 4-1BB at an epitope overlapping with that of its natural ligand (4-1BBL), potentially mimicking physiological 4-1BBL-mediated co-stimulation. As demonstrated through
