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 rod component of the bacterial flagellum polymerizes from the inner membrane across the periplasmic space and stops at a length of 25 nm at the outer membrane. Bushing structures, the P- and L-rings, polymerize around the distal rod and form a pore in the outer membrane. The flagellar hook structure is then added to the distal rod growing outside the cell. Hook polymerization stops after the rod-hook structure reaches approximately 80 nm in length. This study describes mutants in the distal rod protein FlgG that fail to terminate rod growth. The mutant FlgG subunits continue to polymerize close to the length of the normal rod-hook structure of 80 nm. These filamentous rod structures have multiple P-rings and fail to form the L-ring pore at the outer membrane. The flagella grow within the periplasm similar to spirochete flagella. This provides a simple method to evolve intracellular flagella as in spirochetes. The mechanism that couples rod growth termination to the ring assembly and outer membrane penetration exemplifies the importance of stopping points in the construction of a complex macromolecular machine that facilitate efficient coupling to the next step in the assembly pathway.
