The mechanism of inactivation of a 50-pS envelope anion channel during chloroplast protein import.
Article in Biophysical journal, 1999. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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.
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 mechanism of import-competent precursor protein-induced inactivation of a 50-pS anion channel of the chloroplast envelope is investigated using single-channel recordings. The inactivation by precursor protein is the result of the induction of a long-lived closed state of the channel. The mean duration of this state does not depend on precursor concentration. From this it can be concluded that the protein import related anion channel enters the inactive state less frequently when the precursor concentration is lowered, but that the time spent in this state remains the same. Furthermore, it was found that the presence of precursor protein also decreases the mean durations of preexisting open and closed states of the channel. This decrease is found to be dependent on the precursor concentration. From this it is concluded that there is a direct interaction between the precursor protein and a protein complex of which the channel is a constituent. The mean duration of the precursor-induced long-lived closed state does not depend on the length of the translocation-competent precursor. This suggests that the duration of import is independent of precursor length.
