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
backgroundMethicillin-resistant Staphylococcus aureus (MRSA) remains a significant concern in orthopedic surgery, particularly in total knee replacement (TKR), where infection can lead to severe complications. In procedures like TKR, where implants act as a foreign body and potential surface for biofilm formation, infections can lead to severe complications, including delayed healing, and implant failure, and often need multiple revision surgeries. Screening for MRSA before surgery has become a standard practice in many hospitals to reduce the risk of infection. This study aims to evaluate the prevalence of MRSA in patients undergoing TKR and analyze demographic characteristics.
methodsA retrospective analysis was conducted on patients scheduled for TKR. Demographic data, including age, gender, and other relevant clinical information, were extracted from the patient's medical records. MRSA screening was performed as part of the preoperative protocol, and the results were recorded. Descriptive statistics were used to summarize the data and calculate the prevalence of MRSA.
resultsA total of 938 patients underwent MRSA screening prior to TKR. The mean age was 67.25 years (median: 68; range: 33-87). The majority of patients were female, accounting for 706 (75.0%), while 232 (25.0%) were male. MRSA test results revealed that 938 (99.3%) patients tested negative, whereas 6 (0.7%) tested positive. Among MRSA-positive patients, all were aged 60 years or older, suggesting a potential correlation between advanced age and MRSA positivity.
conclusionThis study found a low MRSA prevalence (0.7%) in TKR patients, with all cases occurring in individuals aged ≥60 years. The findings advocate prioritizing preoperative screening in older patients to optimize resource use in low-prevalence settings and highlight the need to investigate TKR-specific risk factors for tailored infection control strategies.
