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

Natural products with diverse functional groups and stereogenic centers have inspired therapeutics and underpin the modern drug discovery process. Their three-dimensional molecular structures need to be unambiguously determined in order to be realized as clinical candidates or to achieve further activity-guided structural optimization. Although recent advances in spectroscopic methods have made it possible for researchers to determine the structures of microgram samples of complex natural products, there is no universally accepted method for determining the relative and absolute configuration of a naturally occurring compound. We report the determination of the full stereostructure of valactamide A, an eight-stereogenic-center-containing fungal metabolite by the synergy of prediction rule-guided analysis and chemical synthesis. The expedient total synthesis resulted in unambiguous verification of the predicted stereochemistry for valactamide A.
