Antimicrobial Sensitivity Patterns of Bacteria Causing Urinary Tract Infections: A Retrospective Study of Elderly Patients Admitted to a Tertiary Care Hospital in Bhubaneswar, India.

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
backgroundThe aging population faces various health challenges, which has increased the burden on healthcare systems. Elderly individuals are more susceptible to urinary tract infections (UTIs), and rising bacterial resistance to antibiotics is a significant global issue.
objectivesThis study compared the bacterial etiology and antibiotic sensitivity testing (AST) patterns of bacteria causing UTIs in elderly patients attending a tertiary care hospital across the intensive care unit (ICU), inpatient department (IPD), and outpatient department (OPD) and analyzed the association of the UTI with the presence of comorbidities and outcomes in the study population. METHODOLOGY: This retrospective study was conducted at the Department of Microbiology at a tertiary care hospital in Bhubaneswar. The demographic, clinical, and microbiological data were collected using a data abstraction form from the electronic medical record from January to December 2022. The study relied entirely on previously documented results. The urine samples received in the laboratory were processed following standard protocol. Identification and AST were done in the Vitek-2 (bioMérieux, Marcy-l'Étoile, France) automated system. AST was interpreted following the Clinical and Laboratory Standards Institute 2021. The Epi Info statistical software, version 7.2.3.1 (Centers for Disease Control and Prevention, Atlanta, GA), was used to analyze the data after loading it into a Microsoft Excel spreadsheet (Microsoft Corporation, Redmond, WA). The results were displayed as mean and standard deviation, frequencies, and percentages. A p value of less than 0.05 is considered statistically significant. Analysis of variance, chi-square test, and Fisher's exact test were employed as association tests.
resultsA total of 4,030 urine samples were processed for culture and sensitivity testing from the study population from January to December 2022. The data were retrospectively compiled and analyzed. The majority of samples (1,600; 39.70%) were received from the ICU, followed by IPD (1,255; 31.14%), and OPD (1,175; 29.15%). Culture positivity was 1,560 (38.70%). The mean age of patients was 69.74 ± 7.52 years, ranging from 60 to 97 years. Males, 2,559 (63.50%), reported more UTIs than females. Chronic kidney disease (CKD, p = 0.0269) and hypertension (HTN, p = 0.0058), associated with UTI, were statistically significant. The most common bacterial isolate was
conclusionThe study showed that UTI was more prevalent in 60-69-year-old people and men.
