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
backgroundSelection breeding is a fundamental approach to the improvement of plant species, enabling the utilization of individuals with superior traits from the natural genetic diversity for targeted purposes. The Hassa district of Hatay province, located in the Eastern Mediterranean region of Türkiye, lies within the boundaries of the historical Levant region and hosts a rich population of wild olive (Olea europaea L. subsp. oleaster) genotypes. In this study, 20 wild olive genotypes selected from this region were evaluated for their potential as rootstocks, with an emphasis on conserving genetic resources. Domat, a well-known olive cultivar, was used as the scion reference for grafting compatibility evaluations.
resultsMorphological assessments revealed that scion lengths among the genotypes ranged from 19.78 ± 15.57 (genotype 31.8.2.36) to 56.67 ± 7.84 cm (genotype 31.8.16.14). Principal component analysis indicated that the first three components explained 82.5% of the total variation. A statistically significant correlation was observed between rootstock diameter and scion diameter (r = 0.46, p < 0.05). Anatomical and histological analyses demonstrated healthy scion development and callus tissue formation in several genotypes, including 31.8.2.19, 31.8.2.34, 31.8.5.18, 31.8.16.5, 31.8.16.12, 31.8.16.13, 31.8.16.14, 31.8.23.2, 31.8.27.5, 31.8.27.16, and 31.8.27.17. In combinations involving genotypes such as 31.8.2.26, 31.8.2.38, 31.8.16.07, 31.8.16.11, 31.8.16.16, and 31.8.23.04, the necrotic layer was effectively absorbed by the callus without disrupting vascular connections, enabling the proper formation of conduction bundles. For genotypes 31.8.2.24, 31.8.2.36, 31.8.2.39, and the control Gemlik rootstock, a dense necrotic layer was detected between the scion and rootstock. However, this did not hinder the formation of vascular connections or conduction bundles.
conclusionsThe findings of this study provide valuable insights into the morphological, anatomical, and histological characteristics of wild olive genotypes, highlighting their potential as rootstocks in breeding programs. These results will support breeders and researchers in the effective utilization and conservation of olive genetic resources.
