The complete chloroplast genome sequences of three Cypripedium species and their phylogenetic analysis.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Cypripedium macranthos Swartz, C. × ventricosum Swartz, and C. shanxiense S. C. Chen were highly promising ornamental plants. In this study, the latest complete chloroplast genome sequence of C. macranthos, C. × ventricosum, and C. shanxiense were reported using correct sample material from their native range, and their phylogenetic relationships with other related species were investigated preliminarily. The whole chloroplast genome lengths of C. macranthos, C. × ventricosum, and C. shanxiense were 181,030 bp, 175,385 bp, and 177,627 bp, respectively, with total GC contents of 34.56%, 34.48%, and 34.42%, respectively. Based on the maximum likelihood phylogenetic tree from the chloroplast genome sequences and internal transcribed spacer (ITS) sequences, it was confirmed that C. × ventricosum is most closely related to C. calceolus, and the idea that C. × ventricosum is an interspecific hybrid between C. calceolus and C. macranthos is supported. By integrating the results of phylogenetic analysis, genomic structural comparison, and considerations of sampling locations, it is evident that the former chloroplast genome of C. macranthos is inaccurate. This study provides crucial information for research on the phylogeny, genetics, and conservation of C. macranthos, C. × ventricosum, and C. shanxiense.
