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

Type I signal peptidases are a widespread family of enzymes which remove the presequences from proteins translocated across cell membranes, including thylakoid and cytoplasmic membranes of cyanobacteria and thylakoid membranes of chloroplasts. We have cloned and sequenced a signal peptidase gene from the thermophilic cyanobacterium Phormidium laminosum which is believed to encode an enzyme common to both membrane systems. The deduced amino acid sequence is 203 residues long and although the overall similarity among signal peptidases is rather low there are a number of identifiable conserved regions present. The P. laminosum enzyme is predicted to have a single transmembrane domain, in contrast to other Gram-negative bacterial sequences, but similar to other type I signal peptidases.
