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
Discovery of novel antibiotics is crucial to counteract bacterial resistance spread. Aiming to expand the available arsenal of last-resort glycopeptide antibiotics (GPAs), we mined the actinobacterial genomes of Pseudonocardiales. We thus identified a biosynthetic gene cluster (BGC) encoding for a GPA with a novel peptide scaffold, not fitting into the existing classification of GPA types. By cultivating the producer strain, Actinokineospora auranticolor DSM 44650, an antibiotic complex-named kineomicins (Kmc)-was identified and characterized by microbiological assays, LC-MS, and MS/MS analyses. A comprehensive model for Kmc biosynthesis was then proposed by a thorough investigation of kineomicin BGC (knm). The structure of the main complex congener (KmcB), resolved by NMR spectroscopy, proved to be unique. Finally, the remarkably high antibiotic production rate, up to >1 g L
