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

TolR is a 142-amino-acid protein required for the import of colicins and bacteriophage and for maintenance of cell envelope integrity. The topology of TolR in the inner membrane was analyzed by two methods. First, bacteria expressing a series of TolR-beta-galactosidase, TolR-alkaline phosphatase, and TolR-beta-lactamase fusions were assayed for the appropriate enzymatic activity. Second, the accessibility of TolR to proteinase K was determined in permeabilized cells and everted vesicles with an antibody elicited against the carboxyl-terminal 70% of TolR. The results are consistent with TolR spanning the inner membrane once via residues 23 to 43 and with the carboxyl-terminal moiety being exposed to the periplasm. Quantitative studies with the anti-TolR antibody indicated the presence of 2 x 10(3) to 3 x 10(3) TolR molecules per cell.
