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
backgroundLocal antibiotic delivery systems-including defensive antibacterial coating (DAC), calcium sulfate beads (CSBs), and antibiotic-loaded bone cement (BC)-have been developed to prevent and manage periprosthetic joint infection (PJI). However, their comparative effectiveness remains unclear.
methodsA systematic search was conducted across PubMed, Cochrane, SpringerLink, ProQuest, and Scopus. Eligible studies involved adults undergoing total hip arthroplasty or total knee arthroplasty and evaluated DAC, CSB, or BC. Inclusion criteria encompassed randomized controlled trials, cohort studies, or matched case-control studies with control groups and relevant outcomes. Key endpoints included infection rate, C-reactive protein, Knee Society Score, Harris Hip Score, and length of hospital stay (LoS). Meta-analyses were done using RStudio with the meta, metafor, and netmeta packages. Effect estimates were presented as odds ratio or mean differences (MDs) with 95% confidence intervals. Evidence quality was assessed using the GRADE approach.
resultsSeventeen studies involving 3672 patients were included. DAC showed the greatest reduction in PJI (odds ratio = 0.14; 95% confidence interval, 0.04 to 0.42; P < 0.001) and a modest improvement in Harris Hip Score (MD = 2.77; P < 0.01), whereas CSB and BC showed less consistent benefits. DAC was also associated with reduced length of hospital stay (MD = -11.29 days; P < 0.05). Meta-regression identified male proportion as a moderator of C-reactive protein and intervention type as a determinant of length of hospital stay.
conclusionDAC demonstrates superior efficacy among local antibiotic carriers in reducing PJI and enhancing postoperative outcomes in total hip arthroplasty and total knee arthroplasty.
