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

A new decalin-containing secondary metabolite, wakodecaline C, was isolated from a fungus Pyrenochaetopsis sp. RK10-F058 by screening structurally interesting metabolites based on LC/MS profiling. The structure including the absolute configuration was determined by a combination of spectroscopic methods including NMR and mass spectrometry, chemical reaction, and calculation of ECD spectra. Wakodecaline C has unique structural features containing a tetrahydrofuran-fused decalin skeleton and tetramic acid moiety, which are connected through a double bond. The compound showed moderate cytotoxicity against HL-60 cells and antimalarial activity against the Plasmodium falciparum 3D7 strain.
