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

The ethyl acetate extract of Tricholaena teneriffae L. roots exhibited significant α-amylase inhibitory activity. Phytochemical analysis of this extract led to the isolation of seven natural products: five 12H-benzo[a]xanthen-12-one derivatives (1-5) and two 7H-benzo[de]anthracen-7-one derivatives (6-7). Among them, compounds 1, 3, 4, 5, and 7 are reported here for the first time as new natural derivatives. Structural elucidation was performed via 1D and 2D NMR spectroscopy, allowing for a precise determination of the substitution patterns of both the benzo[a]xanthen-12-one and benzo[de]anthracen-7-one frameworks. Among them, compounds 6 (IC
