One-year success after debridement, antibiotic therapy, and implant retention for acute hip and knee periprosthetic joint infection: a retrospective cohort study of 62 patients.

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
purposeThe aim of this study was to evaluate the success rate in cases of acute prosthetic joint infection (PJI) of the knee or hip treated with debridement, antibiotics, and implant retention (DAIR), and to identify risk factors associated with treatment failure. MATERIALS AND
methodsA retrospective study was conducted involving adult patients treated with DAIR for PJI of the knee or hip, with a minimum follow-up of 12 months. Success was defined as the absence of signs of recurrence or reinfection 12 months post-DAIR. Cases reviewed for infectious reasons or those on chronic suppressive antibiotic therapy were considered failures. The need for an additional DAIR within 10 days of the first was not classified as failure.
resultsThe final cohort included 62 patients, of whom 35 (56.4%) were male. A total of 45 (72.6%) achieved success with a single DAIR procedure. Failure was significantly more common in patients with polymicrobial infections (58.8% vs. 13.3%; p < 0.01; OR 8.7 [2.3-32.2]) and those with hip PJI (88.2% vs. 48.9%; p = 0.008; OR 7.1 [1.4-33.6]). The presence of persistent wound drainage was associated with a higher risk of failure (52.9% vs. 17.7%; p = 0.002; OR 5.2 [1.6-18.4]). The survival rate at the end of the study was 93.6%.
conclusionsDAIR is an effective option for treating acute PJIs of the knee and hip. The presence of a persistent wound drainage, polymicrobial infections, and hip arthroplasty are independent risk factors for treatment failure.
