Complete plastomes serve as desirable molecular makers for precise identification of Asparagus cochinchinensis (Asparagaceae) and nine other congeneric species frequently utilized as its adulterants.

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
backgroudThe processed tuberous roots of Asparagus cochinchinensis (Asparagaceae), known as Asparagi Radix, have long been used in East Asia (particularly in China) as traditional medicines and play an indispensable role in the pharmaceutical industry. However, the frequent adulteration of Asparagi Radix with processed tuberous roots obtained from nine other congeneric species could potentially compromise the quality control measures for related pharmaceutical products, while also posing challenges to the conservation and rational exploitation of the nine adulterant congeneric species that are also used as traditional ethnomedicines. Given this issue, this study aims to develop a molecular authentication method for the accurate identification of A. cochinchinensis and the nine congeneric adulterants, employing the genome skimming approach to generate complete plastid genomes (plastomes) and nuclear ribosomal DNA (nrDNA) arrays as the candidate molecular markers.
resultsThrough comprehensive phylogenetic and genetic distance analyses based on extensive sampling at both inter- and intra-specific levels, the efficacy of the two candidate molecular markers was assessed by investigating whether their inter-specific genetic divergences align with the taxonomically delineated species boundaries.
conclusionThe results indicated that complete plastomes exhibit superior performance for accurately identifying A. cochinchinensis (the botanical source of Asparagi Radix) and the nine congeneric adulterants, thus can serve as the optimal molecular markers for effective authentication of Asparagi Radix. The desirable discriminative power demonstrated by complete plastomes suggests that the PCR-free molecular authentication method developed in this study will not only contribute to the quality control of pharmaceutical products derived from Asparagi Radix but also facilitate the conservation efforts and rational exploitation of the nine Asparagus species commonly used as adulterants.
