Total Phenolic Content, Antioxidant and Cytotoxic Activity of Three Jacaranda Species (Bignoniaceae).
Article in Chemistry & biodiversity, 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
Species of the genus Jacaranda are often cited for their significant pharmacological potential, including antitumor and antioxidant activity. Therefore, this study aimed to evaluate the antioxidant activity of hot and cold extraction methods for methanolic extracts of leaves and twigs of the species Jacaranda caroba, Jacaranda mimosifolia, and Jacaranda oxyphylla, as well as their cytotoxic capacities. Leaves and twigs were dried and subjected to extraction with hexane, chloroform, and methanol to obtain crude extracts. For antioxidant activity, the cold extraction of J. mimosifolia twigs yielded the best results, while the hot extraction provided the best results for J. caroba leaf extract. Regarding cytotoxic activity against THP-1 and PBMC cell lines, the chloroform and methanolic extracts from J. mimosifolia twigs exhibited the best selectivity indices (SI = 5.17 and SI = 5.50, respectively), results superior to those of the standard drug Cytarabine (SI = 4.4).
