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
A comprehensive phytochemical investigation of Centella asiatica leaves collected in Thailand (sample CAT001) led to the isolation and structural elucidation of eighteen compounds, including two novel polyacetylene glucosides, centellatriolosides A and B. Among the identified constituents, three major triterpenoid glycosides—terminoloside, madecassoside, and asiaticoside—were prominently featured. Terminoloside, newly reported in Thai C. asiatica, was consistently observed in substantial amounts across additional regional samples (CAT002, CAT003, and CAT004), suggesting its broad geographical distribution. Structural elucidation was achieved through detailed spectroscopic analysis, including 1D and 2D NMR techniques. Additionally, a conventional HPLC-UV method employing step-gradient elution was evaluated for the simultaneous separation of six structurally related triterpenes—three glycosides and their corresponding aglycones (terminolic, madecassic, and asiatic acids)—which serve as key quality control markers. Although the method enhanced chromatographic resolution, complete separation of isomeric pairs remained challenging, highlighting the need for advanced analytical approaches in C. asiatica quality assessment.
