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

Introduction: Antigen binding in monoclonal antibodies (mAbs) is traditionally associated with target recognition, but emerging evidence suggests it may also modulate antibody conformation and effector functions. Understanding how antigen engagement impacts the structural organization of therapeutic antibodies and their interaction with immune receptors is essential for optimizing antibody-based therapies. In this study, we investigated, Methods: Accelerated molecular dynamics simulations were performed to investigate the structural and dynamic consequences of antigen binding in two therapeutic mAbs, adalimumab and avelumab. These antibodies were analyzed in different glycosylation states to capture the influence of post translational modifications. Results: Conclusion: These findings suggest that antigen engagement initiates a cascade of coordinated motions that reshape the mAb architecture and regulate its interaction with the immune receptors, offering new insights for the design of functionally optimized therapeutic antibodies.
