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
Rediscovery of known structures is a frequent problem in screening for bioactive bacterial natural products (NPs). Highly parallelized microtiter plate cultivation systems (MPCS) can improve the chance to discover novel NPs by testing a multitude of cultivation conditions simultaneously. An in-depth analysis and comparison of cultivation systems for NP discovery, however, has not been carried out so far. We compared the growth and metabolic footprint of four distinct bacterial species in three MPCS, shake flasks, and stirred tank bioreactors (STR). While the big majority of the cultivation systems provided good growth, we found a considerable divergence in secondary metabolite (SM) formation. The SM space was approximated by the appearance of unique mass features (MFs) in the supernatant extracts throughout the cultivation period. Molecular network analysis was applied to visualize the changes from detected MFs at the molecular level. The cultivation systems had a minor impact on the unicellular growing Bacillus amyloliquefaciens. This impact was more pronounced for the tested filamentous bacteria, resulting in a diversified metabolic footprint. The maximal overlap of 31% of produced MFs indicates a lack of comparability between the cultivation systems, resulting in different entries of growth phases and the formation of associated SMs. The detected SMs and its derivatives exhibited structural modification depending on the cultivation system. A comparison of Streptomyces griseochromogenes NP profile revealed that MPCS yielded less divergent SM formation than shake flasks. Our comprehensive assessment is the first to demonstrate the impact of cultivation systems on the bacterial metabolic footprint, confirming that MPCS provide a robust platform for the parallelization of bacterial cultivations for the discovery of bacterial NPs and accessing the chemical NP space more broadly.
