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

Bispecific antibodies (BsAb) refer to a class of biomacromolecules that are capable of binding two antigens or epitopes simultaneously. This can elicit unique biological effects that cannot be achieved with either individual antibody or two unlinked antibodies. Bispecific antibodies have been used for targeting effector cells to tumor cells, preferential targeting of cells expressing two target biomarkers over cells expressing either target biomarker individually, or to couple two molecular targets on the same cell surface to trigger unique intracellular signaling pathways. Here, we present two related methods that enable direct, rapid assembly of bispecific antibodies from any two "off-the-shelf" Immunoglobulin G (IgG) antibodies, in as little as 1 day. Both workflows can be summarized into two steps: (1) attach a small photoreactive antibody binding domain (pAbBD) fused to SpyCatcher or SpyTag (peptide-protein partners derived from the
