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

New tadalafil analogues were found to be added illegally to an herbal supplement marketed for the enhancement of sexual function. The compounds were separated using flash column chromatography. The structures of the detected tadalafil analogues were elucidated by HPLC-DAD/MS and nuclear magnetic resonance (NMR) spectroscopy. A protonated molecule at m/z 450.16 was detected by LC-MS, corresponding to a molecular formula of C
