Diacarnusins A-F, nor-Terpene Endoperoxides of the Red Sea Sponge Diacarnus erythraeanus.
Article in Journal of natural products, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Six new nor-terpene endoperoxides, diacarnusins A-F (1-6), along with five known ones (7-11), were isolated from the extract of the Red Sea sponge Diacarnus erythraeanus, which presented cytotoxic activity against the colon carcinoma cell line. The structure elucidation was performed by analysis of mass spectrometric and 1D and 2D NMR data. The relative and absolute configurations of the stereocenters of the compounds were deduced based on the Capon and Macleod empirical rule and comparison of the sign of their specific rotations with those of endoperoxides with proven absolute configurations. The cytotoxicity of the pure compounds was evaluated against a panel of cancer cell lines. The structure elucidation and biological activity of the compounds are discussed.
