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
Sour passion fruit (Passiflora edulis) is the most economically important species in the genus Passiflora, mainly due to its edible fruit. Genetic diversity and population structure were analyzed in five P. edulis populations, each comprising 25 individuals, using 28 ISSR molecular markers. The markers exhibited high efficiency and informativeness, with an effective multiplex ratio of 13.99 and a marker index of 3.39. Germplasm included three commercial cultivars (BRS-RC Rubi do Cerrado, FB300-Araguari, and IAC-273/277) and two populations collected from production areas (Bahia and Rio de Janeiro, Brazil). Cluster and Bayesian structure analyses revealed clear genetic differentiation, dividing the accessions into five distinct groups corresponding to their populations of origin. The expected heterozygosity (He) and Shannon's information index (I) varied from He = 0.166 and I = 0.249 to He = 0.203 and I = 0.308. Overall genetic parameters confirmed this structure, with high coefficient of genetic differentiation (0.421) and limited gene flow (0.343 migrants per generation), indicating that 42.1 % of the total genetic variation resides among populations. This finding was consistent with the analysis of molecular variance, which accounted for 45 % of the variation among populations and 55 % within them. Principal coordinates analysis revealed five distinct groups, and the first two principal coordinates analysis axes accounted for 36.8 % of the variation. This study revealed significant genetic diversity and a strong population structure within the analyzed germplasm. These findings highlight its potential as a valuable genetic resource for future Passiflora breeding programs, especially for traits related to fruit quality and adaptation to diverse environmental conditions.
