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

This study aimed to evaluate the yield, color, and chemical composition of Eugenia uniflora essential oils collected from different regions of the Rio de Janeiro (in situ), and to describe the observed diversity based on statistical analyses. A total of 42 samples were collected, essential oils were obtained by hydrodistillation of leaves, with yield expressed as percentage, and analyzed by GC-FID and GC-MS. Descriptive and multivariate statistical analyses were applied for chemical differentiation and classification. Essential oil yields ranged from 0.26% to 3.49%, with the lowest values observed in reddish samples. Seventy-two compounds were detected, of which 49 were identified. Oxygenated sesquiterpenes were the most abundant constituents in the analyzed essential oils, accounting for an average of 69% of the natural product. Cluster analysis revealed three chemical profiles comprising the largest number of samples, a result corroborated by principal component analysis. Nine different chemotypes were identified, most of which were primarily composed of curzerene (1)-a cope rearrangement artifact-and selina-1,3,7(11)-trien-8-one (7). The yield, color, and chemical composition of E. uniflora essential oils varied among the samples analyzed. The identification of multiple chemotypes of E. uniflora highlights the chemical diversity and its potential applicability across various industrial sectors.
