1 · What the graph read from it

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.

2 · The registry

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

To efficiently utilize the olive germplasm resources in the Bailong River Valley region of Longnan, China, the oil content of fresh fruits from 98 olive germplasm samples and three maturity stages (Ⅰ, Ⅱ, Ⅲ) was determined and analyzed. Additionally, 13 oil-related traits were studied using variation, correlation, cluster, and principal component analyses (PCA), aiming to screen excellent germplasm resources through comprehensive evaluation. The results showed that the oil content of fresh fruits exhibits a wide range and increases with maturity: I: 28.00% ~ 60.20%; II: 32.50% ~ 64.60%; III: 34.10% ~ 64.80%. Oleic acid (C18:1) was the predominant fatty acid, and 'Grisha' exhibited the highest content across all three maturity stages. In terms of genetic variation, the coefficients of variation for 13 traits across 98 olive germplasm resources exhibited significant variability. PCA reduced the 13 traits to five principal components, which collectively accounted for a cumulative contribution rate of 77.87%. The comprehensive evaluation has identified the top five olive germplasm resources across three maturity stages, including 'K2', 'Agiou orous', 'FS17', among others. Cluster analysis classified germplasms into three distinct categories (Group I, II, III). Group I is recommended as core germplasm resources suitable for bulk commodity oil production. Group II represents ideal material for cultivating highly stable specialty oils and fats. Meanwhile, Group III offers valuable resources for developing hypoglycemic and lipid-lowering functional oils. This study establishes a foundation for olive breeding, cultivation promotion, and processing in Longnan, China.
