Characterization of ion channels in the plasma membrane of epidermal cells of expanding pea (Pisum sativum arg) leaves.
Article in The Journal of membrane biology, 1994. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
Ion channels in isolated patches of the plasma membrane of pea (Pisum sativum arg) epidermal cells were studied with the patch-clamp technique. One anion and one cation channel were dominantly present in most trials. The anion channel conducts nitrate, halides and malate, with a conductance in symmetrical 100 mM Cl- of 300 pS and can be blocked by SITS when applied to the cytoplasmic side of the membrane. The cation channel poorly discriminates between potassium, sodium and lithium, is not blocked by either TEA or Ba2+, and has a conductance of 35 pS in symmetrical 100 mM K+. The open probability of the cation channel increases with increase of the Ca2+ concentration on the cytoplasmic side of the membrane from 0.1 to 1 microM. The possible role of these two channels in the physiology of epidermal cells is discussed.
