1 · What the graph read from it

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.

2 · The registry

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 protein kinase (MAPK) cascade constitutes a conserved signaling module in eukaryotes. MAPK kinase (MAPKK) plays a crucial role in a MAPK cascade. ZmMEK1 is the first characterized MAPKK gene in maize. Although ZmMEK1 has been studied in detail in biochemical level, the genomic organization of ZmMEK1 gene is obscure. In this research, we clarified ZmMEK1 is a single-copy gene in the maize genome. Southern blot analysis using 3' specific region of ZmMEK1 cDNA as a probe revealed the presence of distinct single bands in each lane of EcoRI and HindIII. Although previous Southern blot analysis using full-length ZmMEK1 cDNA as a probe revealed several hybridizing bands, we showed here that all bands come from one genomic fragment corresponding to ZmMEK1 gene. Furthermore, ZmMEK1 was induced by PEG, abscisic acid (ABA), and salicylic acid (SA) and was down-regulated by NaCl.
