Cultivated Fritillaria cirrhosa bulbs shows comparable chemistry and efficacy to wild-type in Chuanbei Pipa Tangjiang: a metabolomics study.
Article in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Fritillaria cirrhosa bulbs (FC) are key Chuanbei Pipa Tangjiang (CPT) ingredient for cough-sputum relief. Wild scarcity prompted cultivation of tissue-cultured and regenerated plantlet bulbs (TFC/RFC), yet their chemical profiles and antitussive-expectorant equivalence to wild bulbs (WFC) in CPT remain unclear. This study compares the chemical profiles and antitussive-expectorant equivalence of CPT prepared from TFC, RFC and WFC (TCPT, RCPT, and WCPT). We compared the chemical profiles of these three CPT types by LC-MS, and used rat plasma metabolomics and mouse antitussive-expectorant model to assess mechanisms and antitussive-expectorant equivalence. Results showed that five marker constituents (sipeimine, platycodin D, etc.) were quantitatively identical across TCPT, RCPT, WCPT, yielding chemical-profile similarities of 89.9% (TCPT vs. WCPT) and 91.0% (RCPT vs. WCPT). Metabolomics indicated that WCPT-derived platycodin D, peimisine and 4-hydroxycinnamic acid modulated eight pathways, including glutathione, vitamin B6 and selenoamino acid metabolism; TCPT and RCPT concordantly regulated pyroglutamate, aldosterone, associated pathways, with OPLS-DA metabolic-profile concordances of 93.75% and 100% to WCPT. TCPT, RCPT, WCPT presented 37, 46, 32 unique blood-entering constituents, respectively; their functional targets lay within - 20% to + 25% bioequivalence margin. The antitussive-expectorant model revealed no inter-group differences. Thus, TFC, RFC and WFC exhibit high chemical, mechanistic and therapeutic concordance in CPT, with RFC serving as an optimal bioequivalent substitute for WFC.
