Investigation of selective retinoic acid receptor alpha antagonist ER-50891 and related analogs for male contraception.
Article in Archiv der Pharmazie, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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.
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
Retinoic acid receptor alpha (RARα) antagonist ER-50891 and 15 analogs were prepared and tested in vitro for potency and selectivity at RARα, RARβ, and RARγ using transactivation assays. Minor modifications to the parent molecule such as the introduction of a C4 tolyl group in place of the C4 phenyl group on the quinoline moiety slightly increased the RARα selectivity but larger substituents significantly decreased the potency. Replacement of the pyrrole moiety of ER-50891 with triazole, amides, or a double bond produced inactive compounds. ER-50891 was found to be stable in male mouse liver microsomes and was tested in male mice to assess its effects on spermatogenesis. Characteristic, albeit modest and transient, effects on spermatogenesis were observed.
