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
Plants provide an excellent alternative for managing diabetes and are widely utilized in many developing countries including Indonesia. This study aimed to provide comprehensive scientific information on the α-amylase and α-glucosidase inhibitory of the selected medicinal plants used by Sundanese community in West Java. Twelve medicinal plants were extracted individually in ethanol and their total phenolic content (TPC) and total flavonoid content (TFC) were quantified by Folin-Ciocalteu and AlCl₃ colorimetric assays, respectively. Concentration-dependent inhibition of α-amylase and α-glucosidase, as well as DPPH scavenging, were measured in 96-well plates. IC₅₀ values were obtained by non-linear regression. Data were compared by one-way ANOVA (P < 0.001). Autoscaled principal-component analysis (PCA) explored multivariate relationships among TPC, TFC and the bioactivity variables. Among the twelve selected medicinal plants, TPC and TFC varied 20.3-61.9 mgGAE/g and 15.0-64.9 mg/QE g, respectively. S. mahagoni seeds possessed the highest TPC, whereas A. muricata leaves led in TFC. Only S. mahagoni (IC₅₀ = 214 ± 4 µg/mL) and M. charantia (274 ± 5 µg/mL) reached 50% α-amylase inhibition. P. angulata provided the sole measurable α-glucosidase IC₅₀ (438 µg/mL). Furthermore, S. mahagoni exhibited the strongest DPPH scavenging (IC₅₀ = 138.6 µg/mL). PCA explained 69.9% of variance with PC1 (39.5%) loaded positively on α-amylase inhibition (+ 0.83) and TPC (+ 0.81) and PC2 (30.4%) associated with α-glucosidase inhibition (+ 0.81) and TFC (+ 0.62). These data validate Sundanese ethnomedicine and prioritize S.mahagoni and P.angulata for bioactivity-guided isolation and in vivo antidiabetic evaluation.
