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

Two new resistomycin-type pentacyclic polyketide derivatives, designated 1-hydroxy-1-norresistoflavins B (1) and C (2), together with 1R-hydroxy-1-norresistomycin (3) and (6 R)-6,11-Dihydro-7-hydroxy-6-(hydroxymethyl)-8-methoxy-3,9-dimethyl-4H-pyrazino[1,2-b]isoquinolin-4-one (4), were isolated from the marine-derived actinomycete Streptomyces althioticus. Their structures were elucidated by comprehensive spectroscopic analyses, including 1D and 2D NMR and HR-ESIMS data, and the absolute configurations were determined by comparison with experimental and calculated electronic circular dichroism (ECD) spectra. In addition, the absolute configuration of 3 was experimentally determined for the first time based on its ECD data. All isolated compounds were evaluated for cytotoxicity against a panel of six solid cancer cell lines and seven blood cancer cell lines. Compound 3 exhibited significant cytotoxicity against several blood cancer cell lines, with GI
