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
backgroundPeriprosthetic joint infection (PJI) is a challenging complication of arthroplasty. When curative treatment is not feasible, palliative alternatives may be considered. The aim of this study was to evaluate the outcomes of guided persistent fistula (GPF) as a salvage procedure for chronic PJI, focusing on treatment failure, prosthesis retention, and functional preservation.
methodsA retrospective observational study was conducted across five French regional referral centres. Adult patients with chronic PJI treated with GPF as a palliative measure were included. The primary outcome was treatment failure, defined as the occurrence of any major or minor adverse event during follow-up. Secondary outcomes included prosthesis retention, need for major salvage procedures, and ambulatory function. Clinical, microbiological, and outcome data were retrospectively collected.
resultsA total of 51 patients (22 men, 29 women) with a mean age of 75.9 years (range, 48-95) were included. Staphylococcus aureus was the predominant pathogen identified at the infection site. An adjunctive suppressive antibiotic therapy was administered in 11 patients. During follow-up, 21 patients (41.2%) experienced adverse events, including eight minor events (15.7%) requiring re-fistulation and 13 major events (25.5%), comprising two deaths (3.9%), seven prosthesis removals (13.7%), and four amputations (7.8%). Thirty patients (58.8%) remained event-free. Excluding the two deaths, prosthesis retention was achieved in 38 of 49 surviving patients (77.6%).
conclusionGPF may represent a palliative treatment option for selected patients with chronic PJI when curative treatment is not feasible, allowing prosthesis retention in a substantial proportion of cases.
