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
Mitogen-activated kinase (MAPK) signalling pathways are involved in several important processes related to the development and virulence of Fusarium oxysporum. Reversible phosphorylation of the protein members of these pathways is a major regulator of essential biological processes. Among the phosphatases involved in dephosphorylation of MAPKs, type 2C protein phosphatases (PP2Cs) play important roles regulating many developmental strategies and stress responses in yeasts. Nevertheless, the PP2C family is poorly known in filamentous fungi. The F. oxysporum PP2C family includes seven proteins, but only Ptc1 has been studied so far. Here we show the involvement of Ptc6 in the stress response and virulence of F. oxysporum. Expression analysis revealed increased expression of ptc6 in response to cell wall and oxidative stresses. Additionally, targeted inactivation of ptc6 entailed enhanced susceptibility to cell wall stresses caused by Calcofluor White (CFW). We also demonstrate that the lack of Ptc6 deregulates both the Mpk1 phosphorylation induced by CFW and, more importantly, the Fmk1 dephosphorylation induced by pH acidification of the extracellular medium, indicating that Ptc6 is involved in the regulation of these MAPKs. Finally, we showed, for the first time, the involvement of a phosphatase in the invasive growth and virulence of F. oxysporum.
