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 mycobactins, U (1) and V (3), were isolated with ferric-1 (2) and ferric-3 (4) from the culture extracts of Mycolicibacterium septicum IFM 12283. The structures of compounds 1-4 were elucidated via spectral studies, including various NMR analyses. The absolute configurations of compounds 1-4 were deduced by comparing their circular dichroism (CD) spectra with those of mycobactin H (5) and ferric-mycobactin H (6). These compounds exhibited cytotoxicity against the MH7A rheumatoid fibroblast-like synovial cell line.
