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
Phosphorus availability is limited in many natural ecosystems. Plants adapt to phosphate (Pi) deficiency by complex molecular processes. There is growing evidence suggesting that transcription factors are key components in the regulation of these processes. In this study, we characterized the function of ZAT6 (zinc finger of Arabidopsis 6), a cysteine-2/histidine-2 zinc finger transcription factor that is responsive to Pi stress. ZAT6 is induced during Pi starvation and localizes to the nucleus. While the RNAi suppression of ZAT6 appeared to be lethal, its overexpression affects root development and retards seedling growth as a result of decreased Pi acquisition. The ZAT6 overexpression also resulted in altered root architecture of older plants, with consequent changes in Pi acquisition. These results indicate that ZAT6 regulates root development independent of the Pi status of the plant, thereby influencing Pi acquisition and homeostasis. In addition, the expression of several Pi starvation-responsive genes was decreased in ZAT6 overexpressing plants, thereby confirming the role of ZAT6 in regulating Pi homeostasis. This study thus indicates that ZAT6 is a repressor of primary root growth and regulates Pi homeostasis through the control of root architecture. To our knowledge, ZAT6 is the first cysteine-2/histidine-2 zinc finger transcription factor reported to regulate root development and nutrient stress responses.
