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
backgroundThis study aimed to conduct a systematic review and meta-analysis to assess the impact of extended postoperative oral antibiotic prophylaxis (EPOAP) on the risk of reinfection following two-stage exchange arthroplasty for hip and knee periprosthetic joint infection (PJI).
methodsA comprehensive search of PubMed, Embase, and the Cochrane Library was conducted on January 11, 2025. Studies reporting reinfection rates in patients receiving EPOAP after two-stage exchange arthroplasty, compared to those who did not, were included. A random-effects model was used to calculate pooled risk ratios (RRs) and subgroup analyses were performed based on the duration of EPOAP use (> 2 weeks vs. ≤2 weeks) and the joint site (hip or knee).
resultsFive studies, including four retrospective cohort studies and one randomized controlled trial, with a total of 486 knees and 444 hips, were included. The meta-analysis demonstrated that EPOAP significantly reduced the risk of reinfection following two-stage exchange arthroplasty (pooled RR: 0.52; 95% confidence interval [CI]: 0.35, 0.75; p = 0.0006). Subgroup analyses yielded similar findings, with significant reductions in reinfection risk for EPOAP duration > 2 weeks (pooled RR: 0.51; 95% CI: 0.34, 0.78; p = 0.002), hip arthroplasty (pooled RR: 0.37; 95% CI: 0.20, 0.70; p = 0.002), while knee arthroplasty showed a borderline nonsignificant reduction (pooled RR: 0.64; 95% CI: 0.39, 1.04; p = 0.07). Only one cohort study reported a decreased risk of reinfection with EPOAP use ≤ 2 weeks. Two studies assessed adverse events related to EPOAP. No complications were observed among 22 patients in one cohort study, whereas 6 of 22 patients (27%) in an RCT experienced mild gastrointestinal or dermatologic reactions that led to treatment discontinuation. Additionally, another cohort study reported that 16 of 24 reinfection cases (67%) involved organisms resistant to EPOAP.
conclusionsThis meta-analysis suggests that EPOAP is associated with a reduced risk of reinfection following two-stage exchange arthroplasty for hip arthroplasty, while further research is warranted for knee cases. This approach may improve patient outcomes and help optimize post-operative antibiotic management.
