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
Two new 2-benzylfuran compounds, designated as paramyfurans A (1) and B (2), and a new dihydrocoumarin compound, designated as paramylactone (3), along with abscisic acid (4), were isolated from the culture broth of the fungal strain Paramyrothecium sp. BF-1049. The planar structures of 1, 2, and 3 were elucidated based on spectroscopic analyses, including 1D and 2D NMR. Compound 3 was further separated into its enantiomers, namely (+)-paramylactone ((+)-3) and (-)-paramylactone ((-)-3), by HPLC using a chiral column. Their absolute stereochemistry was determined by comparing calculated and experimental ECD spectra. Compounds 1-4 exhibited cytotoxic activity against three mesothelioma cell lines (NCI-H2452, NCI-H2052, and Y-MESO-27), with IC
