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

Geodiamolides are depsipeptides previously isolated from marine sponges that are able to disrupt cytoskeleton microfilaments, inhibit cell migration and invasion, and reverse the malignant phenotype of human breast cancer cell lines to polarized spheroid-like structures. Such cytotoxicity to different cellular targets in breast cancer cells suggests that these molecules might also act in other cancer types such as non-melanoma skin cancer (NMSC), one of the cancer types with high incidence worldwide. Thus, the goal of this work was to study the effects of the marine sponge depsipeptides Geodiamolide A and H (Geo A and Geo H) in human squamous cell carcinoma (A431, NMSC) in order to investigate their effects on cell proliferation and cell death. While no significant statistical difference was observed after Geo H treatment, an expressive dose-dependent reduction in A431 cell viability (IC
