The effect of K(+) on caspase activity of corneal epithelial cells exposed to UVB.
Review in Experimental eye research, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Exposure of human corneal limbal epithelial (HCLE) cells to UVB triggers rapid loss of K(+) and apoptosis via activation of caspases -9, -8 and -3. It has been shown that preventing loss of intracellular K(+) can inhibit apoptosis. The goal of this study was to investigate the effect of K(+) on the UVB-induced caspase activity. HCLE cells were exposed to 150 mJ/cm(2) UVB, followed by measurement of caspase activity in cell lysates. Caspase activity was measured in the presence and absence of 100 mM K(+) in the reaction buffer. UVB-induced activity of caspases -9, -8 and -3 all decreased in the presence of 100 mM K(+). These results suggest that a role of high [K(+)] in the cell is to inhibit caspase activity. Therefore, when cells lose K(+) in response to UVB, caspases are activated and cells go into apoptosis. This supports our hypothesis that K(+) inhibits caspase activity.
