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 patch-clamp technique was used to study the membrane of giant protoplasts from the gram-positive bacterium Streptococcus faecalis, demonstrating the presence of ion-conducting pores in the cytoplasmic membrane of procaryotes. The single channel recordings were characterized by a variety of conductances, ranging up to a few nanoSiemens, arising from stretch-activated, voltage-modulated, cooperative channels. Activation by stretch and voltage took place via both a decrease of the mean closed time and an increase of the mean open time of the channels, which are strictly controlled in intact cells, where they might constitute parts of a membrane apparatus or transport system.
