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
Not susceptible to methicillin Staphylococcus aureus (MRSA), is a potentially harmful bacteria that is resistant to the most important antimicrobial agents. Because MRSA is so resistant to many antibiotics, it can cause illnesses by forming biofilms. The aim of this study was to assess the nasal carriage rate of biofilm-producing methicillin-resistant Staphylococcus aureus (MRSA) and its associated factors among HealthCare Workers at Wachemo University Nigist Ellen Mohammed Memorial Comprehensive Specialized Hospital, Central Ethiopia. This cross-sectional study, carried out at Wachemo University Nigist Ellen Mohammed Memorial Comprehensive Specialized Hospital, Central Ethiopia from August 1 to November 30, 2023. Nasal swab samples from 294 healthcare workers (HCWs) were obtained using sterile cotton swabs. Bacterial isolates were identified using standard culture methods on Mannitol Salt and Blood Agar, while antimicrobial susceptibility testing and biofilm formation assessments followed the CLSI 2023 (M100, 33rd edition) guidelines via the Kirby-Bauer disk diffusion methods. All laboratory analyses were performed in triplicate to ensure consistency. Data were double-entered into Epi Data version 4.6 and cross-checked for accuracy. Missing or inconsistent data were verified against original laboratory records and latterly then, exported to SPSS V25 for analysis. Descriptive statistics and logistic regression were applied for statistical evaluation, with a p-value of ≤ 0.05 regarded as statistically significant. In this study, the occurrence rates of S. aureus, MRSA, and biofilm-producing MRSA were 98 out of 294 isolated strains (33.4%), 41 out of 294 isolated strains (13.9%), and 28 out of 294 isolated strains (9.5%), respectively. The MRSA strains exhibited high sensitivity to linezolid, rifampicin, and vancomycin while showing resistance to cefoxitin, cotrimoxazole, and ciprofloxacin. A history of prior hospitalization (length of stay in the hospital) was statistically significant for the colonization of biofilm-producing MRSA, with an adjusted odds ratio of 10.00 (95% CI: 1.36-73.3; P = 0.024). MRSA and MRSA that produces biofilms were found to be 41.8% and 68.3% prevalent overall in the study area, respectively. Biofilm-producing MRSA is a potential cause of healthcare-associated diseases. Therefore, these findings emphasize the urgent need for improved infection-prevention practices and routine screening of healthcare workers to mitigate the risk of healthcare-associated infections.
