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
The process of biofilm formation is intricate and multifaceted, requiring the individual cells to secrete extracellular polymeric substances (EPS) that subsequently aggregate and adhere to various surfaces. The issue of biofilms is a significant concern for public health due to the increased resistance of microorganisms associated with biofilms to antimicrobial agents. The current study describes the whole genome and corresponding functions of a biofilm inhibiting and eradicating actinobacteria isolate identified as Nocardiopsis lucentensis EMB25. The N. lucentensis EMB25 has 6.5 Mbp genome with 71.62% GC content. The genome analysis by BLAST Ring Image Generator (BRIG) revealed it to be closely related to Nocardiopsis dassonvillei NOCA502F. Interestingly, based on orthologous functional groups reflected by average nucleotide identity (ANI) analysis, it was 81.48% similar to N. arvandica DSM4527. Also, it produces lanthipeptides and linear azole(in)e-containing peptides (LAPs) akin to N. arvandica. The secondary metabolite search revealed the presence of major gene clusters involved in terpene, ectoine, siderophores, Lanthipeptides, RiPP-like, and T1PKS biosynthesis. After 24 h of treatment, the cell-free extract effectively eradicates the pre-existing biofilm of P. aeruginosa PseA. Also, the isolated bacteria exhibited antibacterial activity against MRSA, Staphylococcus aureus and Bacillus subtilis bacteria. Overall, this finding offers valuable insights into the identification of BGCs, which contain enzymes that play a role in the biosynthesis of natural products. Specifically, it sheds light on the functional aspects of these BGCs in relation to N. lucentensis.
