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
Excessive low-affinity Na(+) uptake is toxic to the growth of glycophytic plants. Recently, several reports have suggested that the interaction between K(+) and Na(+) uptake might represent a key factor in determining the Na(+) tolerance of plants. We investigated the effects of K(+) starvation on Na(+) and K(+) uptake mechanisms in the plasma membrane of wheat (Triticum aestivum L.) root cortex cells using the patch-clamp technique. Unexpectedly, K(+) starvation of wheat seedlings was found to enhance the magnitude and frequency of occurrence of time-dependent inward-rectifying K(+) channel currents (I(K)(+)(in)). We examined whether the transcription of a wheat root K(+)(in) channel gene is induced by K(+) starvation. A cDNA coding for a wheat root K(+) channel homolog, TaAKT1 (accession no. AF207745), was isolated. TaAKT1 mRNA levels were up-regulated in roots in response to withdrawal of K(+) from the growth medium. Furthermore, K(+) starvation caused an enhancement of instantaneous Na(+) currents (I(Na)(+)). Electrophysiological analyses suggested that I(K)(+)(in) and I(Na)(+) are not mediated by the same transport protein based on: (a) different activation curves, (b) different time dependencies, (c) different sensitivities to external Ca(2+), and (d) different cation selectivities. These data implicate a role for I(Na)(+) in Na(+) uptake and stress during K(+) starvation, and indicate that K(+)(in) channels may contribute to K(+)-starvation-induced K(+) uptake in wheat roots.
