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 Arabidopsis guard cell anion channel SLAC1 is essential for stomatal closure in response to various endogenous and environmental stimuli. Interestingly, here we reveal an unexpected impairment of slac1 alleles on stomatal opening. We report that mutations in SLAC1 unexpectedly slow stomatal opening induced by light, low CO(2) and elevated air humidity in intact plants and that this is caused by the severely reduced activity of inward K(+) (K(+)(in)) channels in slac1 guard cells. Expression of channels and transporters involved in stomatal opening showed small but significant reductions in transcript levels in slac1 guard cells; however, this was deemed insufficient to explain the severely impaired K(+)(in) channel activity in slac1. We further examined resting cytosolic Ca(2+) concentration ([Ca(2+)](cyt)) and K(+)(in) channel sensitivity to [Ca(2+)](cyt) in slac1. These experiments showed higher resting [Ca(2+)](cyt) in slac1 guard cells and that reducing [Ca(2+)](cyt) to < 10 nM rapidly restored the activity of K(+)(in) channels in slac1 closer to wild-type levels. These findings demonstrate an unanticipated compensatory feedback control in plant stomatal regulation, which counteracts the impaired stomatal closing response of slac1, by down-regulating stomatal opening mechanisms and implicates enhanced [Ca(2+)](cyt) sensitivity priming as a mechanistic basis for the down-regulated K(+)(in) channel activity.
