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
Uropathogenic Escherichia coli (UPECs) are the predominant cause of asymptomatic bacteriuria (ABU) and symptomatic UTI. In this study, multidrug-resistant (MDR) ABU-UPECs from hospitalized patients of Kolkata, India, were characterized with respect to their ESBL phenotype, acquisition of β-lactamase genes, mobile genetic elements (MGEs), phylotype property, ERIC-PCR profile, sequence types (STs), clonal complexes (CCs) and evolutionary and quantitative relationships and compared to the symptomatic ones to understand their epidemiology and evolutionary origin. Statistically significant incidence of ESBL producers, β-lactamase genes, MGEs and novel phylotype property (NPP) among ABU-UPECs similar to the symptomatic ones indicated the probable incidence of chromosomal plasticity on resistance gene acquisition through MGEs due to indiscriminate drug usage. ERIC-PCR typing and MLST analysis showed clonal heterogeneity and predominance of ST940 (CC448) among asymptomatic isolates akin to symptomatic ones along with the evidence of zoonotic transmissions. Minimum spanning tree analysis showed a close association between ABU-UPEC with known and unidentified STs having NPPs with isolates that belonged to phylogroups clade I, D, and B2. This is the first study that reported the occurrence of MGEs and NPPs among ABU-UPECs with the predominance of ESBL production which displayed the deleterious effect of MDR among this pathogen demanding alternative therapeutic interventions. Moreover, this study for the first time attempted to introduce a new approach to ascertain the phylotype property of unassigned UPECs. Withal, increased recognition, proper understanding and characterization of ABU-UPECs with the implementation of appropriate therapeutic measures against them when necessary are the need of the era which otherwise might lead to serious complications in the vulnerable population.
