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
This study investigated the effects of different drying techniques and green extraction methods on bioactive compounds in hop leaves, typically considered as waste material. Freeze-drying (FD) and oven-drying (OD) were compared for drying the leaves of five hop varieties, while the study focused on the use of microwave (MAE) and ultrasound (UAE) as innovative extraction techniques. The influence of these factors was then evaluated on several bioactive compounds, including polyphenols, flavonoids, pigments, and xanthohumol, as well as the antioxidant capacity and α-glucosidase inhibition of the extracts obtained. MAE yielded higher total polyphenol and flavan content (TPC and FLC, respectively) values than UAE. Similarly, FD samples showed higher TPC and FLC values than OD ones, whereas chlorophyll b was consistently more abundant than chlorophyll a in all samples. HPLC analysis identified catechin, epigallocatechin gallate, and p-hydroxybenzoic acid as the predominant phenolic compounds. Xanthohumol concentrations ranged from 0.04 ± 0.00 to 1.12 ± 0.03 mg g
