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
Berberis vulgaris L. is a shrub exhibiting significant morphological and biochemical diversity. This study evaluated nine wild genotypes from Isfahan Province, Iran, based on 21 morphological and biochemical traits. Fruit length varied from 0.6 to 1.07 cm, width from 0.47 to 0.72 cm, and weight from 0.14 to 0.26 g, with colors ranging from light yellow to dark red. Pearson correlation analysis revealed key relationships: fruit weight correlated positively with seed length (r = 0.50), fruit color had a strong negative correlation with fruit length (r = - 0.68) and a positive correlation with leaf color (r = 0.74). The number of fruits per panicle correlated negatively with seed width (r = - 0.73), while fresh fruit weight correlated positively with leaf blade length (r = 0.79). Biochemical analysis revealed significant antioxidant activity (ranging from 89.20 to 97.10%), which correlated with phenolic content (5.18-14.34 mg GAE/g DW) and flavonoid content (5.3-16.86 mg QE/g DW). Sample 2 had the highest total phenolics (TP) content (14.34 mg GAE/g DW.), flavonoids (13.83 mg QE/g DW), whereas sample 7 exhibited the highest flavonoid concentration (16.86 mg QE/g DW) and sample 3 showed the strong antioxidant capacity (97.10%). Hierarchical clustering grouped genotypes into three clusters: Cluster I (samples 7 and 8) with distinct biochemical profiles; Cluster II (samples 1 and 2) with darker fruits and higher phenolics; Cluster III with lighter fruits and lower biochemical levels. These results highlight the genetic diversity and medicinal potential of B. vulgaris, suggesting fruit color and morphological traits as useful markers for selecting genotypes with high antioxidant capacity. Conservation and breeding efforts should prioritize these valuable wild resources for pharmaceutical and nutraceutical uses. Future studies integrating molecular markers with morphological and biochemical traits will provide deeper insights into the genetic basis of variability and support targeted breeding programs.
