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
backgroundPlatostoma palustre (Blume) A. J. Paton is an economic crop with medicinal and edible properties. WRKY transcription factors are widely involved in the growth and development, response to adversity stress, and hormone transduction of plants. The identification of the WRKY gene family has been completed in many plants, however, it has not yet been identified and analyzed at the genome-wide level in P. palustre.
resultsIn this study, we identified 133 PpWRKY gene family members (PpWRKYs) at the whole genome level of P. palustre, which were unevenly distributed on 15 chromosomes. Based on their protein structure and phylogenetic characteristics, the 133 PpWRKYs were divided into 3 subgroups. Segmental duplication events might play a crucial role in the expansion of the PpWRKY gene family. Through the transcriptome expression data analysis, the expression profiles of PpWRKY genes under Cd, red light, salt, and drought stresses were analyzed in this study, suggesting that WRKY transcription factors may play a crucial role in responding to different abiotic stresses in P. palustre. Notably, PpWRKY92 exhibited simultaneous responses to Cd, light intensity, salt, and drought stresses. Additionally, PpWRKY21, 75, 90, 52, 124, 39, 115, 122, 20, and 76 demonstrated a strong correlation with both monosaccharides and flavonoids. Taken together, PpWRKY20, 39, 75, 76, 90, 92, 115, 122, and 124 were found to be associated with the abiotic stress response and polysaccharides and flavonoids biosynthesis in P. palustre, except the low-expressed PpWRKY21 and 52.
conclusionThe present study laid the foundation for the abiotic stress response and metabolite regulation of this gene family in P. palustre.
