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

The emergence of Carbapenemase-producing Klebsiella pneumoniae (CP-KP) strains is becoming a significant global concern. Rising resistance rates in these strains significantly impact available treatment options. Therefore, this present research aims to identify the existence of antibiotic-resistance genes in clinical isolates of CP-KP strains. Whole-genome sequencing data from 17 CP-KP isolates were analyzed to identify genetic variants associated with antibiotic resistance. Among the 85 variants, a deleterious mutation, E466D, was identified in DNA gyrase B (GyrB), associated with fluoroquinolone (FQ) resistance. Therefore, flavonoids were used to target mutated GyrB. Flavonoids have been extensively investigated for their antibacterial properties, as they tend to inhibit the growth of many pathogenic microorganisms, including multidrug-resistant bacteria. A total of 222 flavonoids were subjected to virtual screening against the GyrB. The docking affinity of all the ligands with GyrB was within the range of - 3.7 to - 7.9 kcal mol
