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
backgroundChia (Salvia hispanica L.) is recognized for its nutritional value and health-promoting compounds, including flavonoids.
aimThis study utilized DNA barcoding to identify and differentiate two novel chia genotypes, CACH-W and CACH-B, providing insights for breeding programs and genetic resource conservation (CA refers to the developer and CH refer to Chia).
methodsDNA was extracted from controlled samples and analyzed using five barcode markers: trnH-psbA, matK, rpoC1, rbcL, and ITS. Genetic diversity was evaluated through phylogenetic analysis with appropriate bioinformatics tools.
resultsDNA barcoding using five markers (trnH-psbA, matK, rpoC1, rbcL, and ITS) successfully amplified sequences of 930 bp, 1520 bp, 2295 bp, 1910 bp, and 1630 bp, respectively. Among them, rbcL, rpoC1, and ITS effectively differentiated the two genotypes, and phylogenetic analysis confirmed their genetic identity and relationship with existing (Salvia hispanica L.) sequences. Functional analyses highlighted the conserved roles of key genes, including rbcL (carbon fixation), rpoC1 (chloroplast transcription), and matK (RNA splicing). The white genotype (CACH-W) outperformed the black genotype (CACH-B) in germination, physiological, and agronomic traits, achieving a higher seedling vigor index (11.68 vs. 8.51), longer radicle (6.94 cm vs. 5.02 cm), and greater total phenolic content (31.92 mg/g vs. 28.95 mg/g). Agronomically, CACH-W showed superior plant height, spike weight, and seed yield (1003.83 kg/feddan vs. 606.46 kg/feddan), making it a promising candidate for cultivation and breeding.
conclusionThis study demonstrates the effectiveness of certain plastome gene sequences in identifying and distinguishing chia varieties, offering a reliable tool for breeding, quality control, and germplasm conservation. The white genotype (CACH-W) outperformed the black genotype (CACH-B) in germination, physiological, and agronomic traits, achieving a higher seedling vigor index, longer radicle, and greater total phenolic content. Agronomically, CACH-W showed superior plant height, spike weight, and seed yield, making it a promising candidate for cultivation and breeding. The results also support the integration of marker-assisted selection for developing chia varieties with improved traits, enhancing their commercial and agricultural value.
