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
Calcium-dependent protein kinases (CDPKs) are key components of calcium regulated signaling cascades in plants. In this work, isoform StCDPK3 from Solanum tuberosum was studied and fully described. StCDPK3 encodes a 63 kDa protein with an N-terminal variable domain (NTV), rich in prolines and glutamines, which presents myristoylation and palmitoylation consensus sites and a PEST sequence indicative of rapid protein degradation. StCDPK3 gene (circa 11 kb) is localized in chromosome 3, shares the eight exons and seven introns structure with other isoforms from subgroup IIa and contains an additional intron in the 5'UTR region. StCDPK3 expression is ubiquitous being transcripts more abundant in early elongating stolons (ES), leaves and roots, however isoform specific antibodies only detected the protein in leaf particulate extracts. The recombinant 6xHis-StCDPK3 is an active kinase that differs in its kinetic parameters and calcium requirements from StCDPK1 and 2 isoforms. In vitro, StCDPK3 undergoes autophosphorylation regardless of the addition of calcium. The StCDPK3 promoter region (circa 1,800 bp) was subcloned by genome walking and fused to GUS. Light and ABRE responsive elements were identified in the promoter region as well as elements associated to expression in roots. StCDPK3 expression was enhanced by ABA while GA decreased it. Potato transgenic lines harboring StCDPK3 promoter∷GUS construct were generated by Agrobacterium tumefaciens mediated plant transformation. Promoter activity was detected in leaves, root tips and branching points, early ES, tuber eyes and developing sprouts indicating that StCDPK3 is expressed in actively growing organs.
