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
Tiandong is a vital traditional Chinese herbal medicine. It is derived from the tuber root of the Asparagus cochinchinensis according to the Pharmacopoeia of the people's republic of China (2020 Edition). On account of the similar morphology, Asparagus meioclados and Asparagus munitus were used as Tian-Dong in southwest China. Chloroplast (cp) genomes are highly active genetic components of plants and play an extremely important role in improving the efficiency of the identification of plant species. To differentiate the medicinal plants belonging to the genus Asparagus, we sequenced and analyzed the complete plastomes (plastid genomes) of A. meioclados and A. munitus and obtained two plastomes whose length changed to 156,515 bp and 156,381 bp, respectively. A total of 111 unique genes have been detected in plastome, which included 78 protein-coding genes, 29 tRNA genes and 4 rRNA genes. In plastomes of A. meioclados and A. munitus, 14,685 and 14,987 codons were detected, among which 9942 and 10,207 had the relative synonymous codon usage (RSCU) values higher than 1, respectively. A. meioclados and A. munitus have 26 SSRs patterns, among which A. meioclados was 25 and A. munitus 21. The average Ka/Ks value was 0.36, and positive selection was detected in genes of the photosynthetic system (ndhF and rbcL) in Asparagus species. To perform the comparative analysis of plastomes, the two newly sequenced plastomes of the A. meioclados and A. munitus species were compared with that of A. cochinchinensis, and 12 hotspots, including 5 coding regions and 7 inter-genomic regions, were identified. Based on the whole plastome of Asparagus, 2 divergent hotspots (accD and rpl32-trnL-UAG) and 1 international barcode fragment (rbcL) were screened, which may be used as particular molecular markers for the identification of Asparagus species. In addition, we determined the phylogenetic relationship between A. meioclados and A. munitus in the genus Asparagus. This study enriches our knowledge of the molecular evolutionary relationships of the Asparagus genus and provides treasured data records for species identification, molecular breeding, and evolutionary analysis of this genus.
