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 bacteriophage T4 DNA packaging machine consists of a molecular motor assembled at the portal vertex of an icosahedral head. The ATP-powered motor packages the 56-µm-long, 170-kb viral genome into 120 nm × 86 nm head to near crystalline density. We engineered this machine to deliver genes and proteins into mammalian cells. DNA molecules were translocated into emptied phage head and its outer surface was decorated with proteins fused to outer capsid proteins, highly antigenic outer capsid protein (Hoc) and small outer capsid protein (Soc). T4 nanoparticles carrying reporter genes, vaccine candidates, functional enzymes, and targeting ligands were efficiently delivered into cells or targeted to antigen-presenting dendritic cells, and the delivered genes were abundantly expressed in vitro and in vivo. Mice delivered with a single dose of F1-V plague vaccine containing both gene and protein in the T4 head elicited robust antibody and cellular immune responses. This "progene delivery" approach might lead to new types of vaccines and genetic therapies.
