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
backgroundMost studies investigating the role of sonication fluid culture on periprosthetic joint infections (PJIs) focused on diagnostic accuracy, without assessing its potential impact on patient management. This study aims to evaluate how the use of sonication fluid culture may alter the diagnosis and management of PJI.
methodsIncluded were 429 patients (mean age [SD], 68 [11] year; 65% male) who underwent explantation of a knee or hip prosthesis due to suspected PJI or aseptic causes. Because the Infectious Diseases Society of America (IDSA) PJI criteria do not include sonication in the diagnostic definition, we compared sonication fluid culture results with intraoperative tissue cultures patient-per-patient. In contrast, the European Bone and Joint Society (EBJIS) criteria include both sonication and tissue cultures. For EBJIS-confirmed criteria, we calculated the proportion of cases meeting the sonication fluid culture criterion of >50 colony-forming units (CFU)/ ml, and the number of cases where sonication identified additional microorganisms than tissues.
resultsAmong 95 PJI cases defined by IDSA criteria, sonication fluid culture would not alter patient management in 61 (64.2%) cases, as findings were fully concordant with tissue cultures. In 8 (8.4%) cases, sonication detected an additional virulent microorganism that could influence antibiotic selection. According to EBJIS criteria, 113 cases were classified as confirmed; 50 (44.2%) met the definition based solely on a positive sonication fluid culture >50 CFU/ml. In 10 of these 50 patients (20%), sonication influenced antibiotic selection by identifying additional low-virulence microorganisms.
conclusionsSonication fluid culture may influence clinical management in approximately 8% to 20% of PJI cases.
