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
backgroundAcute periprosthetic joint infection (PJI) represents a major cause of early failure following total knee arthroplasty (TKA). In selected cases, implant retention strategies such as debridement, antibiotics, and implant retention (DAIR), including modified techniques such as debridement, antibiotic pearls, and retention of the implant (DAPRI), may be considered. However, the success of these approaches is strongly influenced by the condition of the surrounding soft tissues. In the presence of compromised or tenuous wound conditions, soft tissue reconstruction may play a critical adjunctive role. This review aims to evaluate the role of the gastrocnemius flap as an adjunct to implant retention strategies in the management of acute PJI following TKA.
methodsA systematic review was conducted in accordance with PRISMA guidelines. After screening 27 studies, five retrospective case series met the inclusion criteria, comprising a total of 73 patients with a mean follow-up of 48.7 months.
resultsThe medial gastrocnemius flap was the most used technique, accounting for approximately 70% of cases. Infection clearance rates ranged from 66% to 77%, while prosthesis retention was achieved in nearly 79% of patients. Gastrocnemius flap coverage was applied in conjunction with different PJI treatment strategies, including staged revision procedures and implant retention approaches. Early flap application, particularly when combined with debridement and implant retention in the presence of compromised soft tissues, was associated with improved wound healing and limb salvage, although the level of evidence remains limited.
conclusionsGastrocnemius flap reconstruction appears to be a useful adjunct in selected patients undergoing implant retention strategies for acute PJI following TKA, particularly in the presence of compromised soft tissue conditions. Nevertheless, the current evidence is based on low-level, non-comparative studies, and definitive conclusions regarding its routine or preventive use cannot be drawn. Further prospective and comparative studies are required to better define indications, timing, and expected outcomes.
