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
objectiveThis study aimed to investigate the effect of the leaf extracts of Syzygium jambos and Solanum guaraniticum on the δ-aminolevulinate dehydratase (δ-ALA-D) activity, their antioxidant activity and potential protective action on oxidatively stressed erythrocytes, in order to demonstrate the safety or toxicity of the plant.
methodsIn erythrocyte samples, the effect of both extracts on δ-ALA-D activity, H2O2-induced oxidative stress, and 2,2'azobis (2-amidinopropane) (AAPH)-induced hemolysis was evaluated, as well as some antioxidant mechanisms.
resultsBoth extracts inhibited δ-ALA-D activity (S. guaraniticum > S. jambos), and an involvement of the zinc ion of the δ-ALA-D structure on the inhibition of enzyme activity was verified. S. jambos leaf extract showed marked efficiency in countering H2O2-induced lipid peroxidation and in maintaining cellular integrity against AAPH-induced hemolysis. Furthermore, S. jambos exhibited greater H2O2 scavenging activity and stronger reduction power than S. guaraniticum. DISCUSSION: Both extracts bear potent antioxidant property as an important beneficial effect. However, the inhibition of δ-ALA-D activity suggests a possible harmful effect of these vegetal preparations and indicates the need for further investigation regarding their toxicological properties. All together, these data represent a significant contribution to the knowledge of these plants, both to the scientific community and to the folk medicine.
