Article in Marine drugs, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
There is a variety of antineoplastic drugs that are based on natural compounds from ecological niches with high evolutionary pressure. We used two cell lines (Jurkat J16 and Ramos) in a screening to assess 300 different naturally occurring compounds with regard to their antineoplastic activity. The results of the compounds 4,6-dibromo-2-(2',4'-dibromophenoxy)phenol (P01F03), 4,5,6-tribromo-2-(2',4'-dibromophenoxy)phenol (P01F08), and 5-epi-nakijinone Q (P03F03) prompted us to perform further research. Using viability and apoptosis assays on the cell lines of primary human leukemic and normal hematopoietic cells, we found that P01F08 induced apoptosis in the cell lines at IC50 values between 1.61 and 2.95 μM after 72 h. IC50 values of peripheral blood mononuclear cells (PBMNCs) from healthy donors were higher, demonstrating that the cytotoxicity in the cell lines reached 50%, while normal PBMNCs were hardly affected. The colony-forming unit assay showed that the hematopoietic progenitor cells were not significantly affected in their growth by P01F08 at a concentration of 3 μM. P01F08 showed a 3.2-fold lower IC50 value in primary leukemic cells [acute myeloid leukemia (AML)] compared to the PBMNC of healthy donors. We could confirm the antineoplastic effect of 5-epi-nakijinone Q (P03F03) on the cell lines via the induction of apoptosis but noted a similarly strong cytotoxic effect on normal PBMNCs.
