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

Myxoglucamides, natural products recently isolated from Cystobacterineae sp., are featured by an unprecedented vinyl-substituted α-keto-γ-amino acid that is linked to a glycosylated 14-methyl-pentadecanoic acid. Thus, they unite elements from three biomolecular classes in a compact glycolipopeptide. To elucidate the biological relevance of this arrangement, we searched for molecular targets by activity-based protein profiling (ABPP)-although a phenotypic bioactivity has not been reported. An access to the compound class was established through the first total synthesis of myxoglucamide A in 11 steps. A proteome-wide ABPP study led to the identification of aldo-keto reductase 1C3 (AKR1C3) as the primary target of myxoglucamides in human cells. AKR1C3 is an oncogenic factor involved in prostaglandin and steroid synthesis, promoting the growth, proliferation, and metastasis of carcinoma cells. The functional inhibition of AKR1C3 by a competitive mechanism (IC
