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
Escherichia coli is one of the most common causes of urinary tract infections. However, a recent upsurge in antibiotic resistance among uropathogenic E. coli (UPEC) strains has provided an impetus to explore alternative antibacterial compounds to encounter this major issue. In this study, a lytic phage against multi-drug-resistant (MDR) UPEC strains was isolated and characterized. The isolated Escherichia phage FS2B of class Caudoviricetes exhibited high lytic activity, high burst size, and a small adsorption and latent time. The phage also exhibited a broad host range and inactivated 69.8% of the collected clinical, and 64.8% of the identified MDR UPEC strains. Further, whole genome sequencing revealed that the phage was 77,407 bp long, having a dsDNA with 124 coding regions. Annotation studies confirmed that the phage carried all the genes associated with lytic life cycle and all lysogeny related genes were absent in the genome. Further, synergism studies of the phage FS2B with antibiotics demonstrated a positive synergistic association among them. The present study therefore concluded that the phage FS2B possesses an immense potential to serve as a novel candidate for treatment of MDR UPEC strains.
