Extended oral antibiotics fail to reduce surgical site infection in orthopedic surgeries: A comparative study.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundSurgical site infection (SSI) is associated with a significant burden in orthopedic surgeries, leading to increased morbidity, prolonged hospital stays, and higher healthcare costs. Despite the widespread use of prophylactic antibiotics to reduce the risk of infection, the optimal duration for antibiotic administration remains controversial. Newer studies reported controversial results compared to existing guidelines; therefore, we aimed to compare the efficacy and post-operative complications of short-term (<24 hours) and extended oral antibiotics in reducing infection rates following orthopedic surgeries.
methodsIn this retrospective study, patients who underwent orthopedic surgeries, including total knee arthroplasty (TKA), total hip arthroplasty (THA), anterior cruciate ligament (ACL) reconstruction, and hip internal fixation, were recruited from the hospital data registry. Patients were divided into two groups of short-term (<24 hours) and extended oral antibiotics groups based on the duration of prophylactic antibiotic use. The infection rate during three months after the surgery and the incidence of antibiotic-related adverse events were compared between the groups.
resultsOf the 398 patients in the study, 246 received short-term, and 152 received extended oral antibiotics. There was no significant difference between the short-term (2.8%) and extended (4.6%) groups with respect to the rate of SSI (P = 0.35). The patients in the extended antibiotic group demonstrated more post-operative complications compared to the short-term group (36.2% Vs. 22.8%, P = 0.004).
conclusionOur findings demonstrated that extended oral antibiotics did not reduce the rate of SSI following orthopedic surgeries compared to short-term prophylaxis. Furthermore, patients who received prolonged antibiotic demonstrated a higher incidence of postoperative complications. Our study supports the recommendation not to use extended prophylactic oral antibiotics over 24 hours in orthopedic surgeries.
