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

backgroundEmerging of endophytic fungi as potent camptothecin producers raise the hope for its commercial production, due to their rapid growth and feasibility of metabolic engineering, nevertheless, their loss of productivity with the fungal storage and subculturing is the challenge. Thus, screening for unique fungal isolate with sustainable camptothecin productivity is the objective of this work.

resultsThe camptothecin productivity of the fungal endophytes of wild and in vitro cultured Astragalus fruticosus was evaluated. Aspergillus flavus ER, endophyte of A. fruticosus explant, was the potent producer (51.7 µg/l), the chemical identity of putative compound was resolved by UV, HPLC and LC-MS/MS analyses. The purified A. flavus camptothecin displayed a significant activity against HEPG-2 (IC

conclusionThis is the first study deciphering the feasibility of A. flavus for sustainable production of camptothecin upon addition of A. fruticosus extracts, that could be a new platform for camptothecin scaling-up.
