1 · What the graph read from it

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.

2 · The registry

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

objectiveTo investigate the correlation between magnetic resonance imaging (MRI) lamellated hyperintense synovitis and periprosthetic infection of hip arthroplasty and estimate its value in the diagnosis of infection after hip replacement.

methodsA retrospective analysis of 50 patients who underwent MRI from January 2016 to June 2019 after hip replacement was performed. The MRI scanning was performed with a 1.5T clinical imaging unit using SEMAC protocols. A total of 25 patients (cohort 1) showed infected total hip arthroplasty, and 25 patients had non-infected arthroplasty as controls (cohort 2). Two musculoskeletal radiologists, blinded to the clinical diagnosis, reviewed all the images for the presence of lamellated hyperintense synovitis independently. The cases were rereviewed by each reader after 2 weeks. The sensitivity, specificity, positive predictive value, and negative predictive value were calculated using the first reads. The Kappa statistic was used to assess inter-observer and intra-observer reliability.

resultsThe incidence of lamellated hyperintense synovitis was 76%-88% in the experimental group and 8%-16% in the control group. The sensitivity of lamellated hyperintense synovitis for infection was 0.80-0.88 (95% confidence interval [CI]:0.59 - 0.97), the specificity was 0.84~0.92 (95% CI: 0.64  -0.99), the positive predictive value 0.83-0.92 (95% CI: 0.67 - 0.98), the negative predictive value 0.81 - 0.88 (95% CI: 0.65 - 0.96). The agreement between two readers was substantial (Kappa = 0.76, 95% CI: 0.58 - 0.94, P < 0.05). There were moderate inter-observer agreements for both readers, reader 1 (Kappa = 0.48, 95%CI: 0.23 - 0.72, P < 0.05) and reader 2 (Kappa = 0.44,95% CI: 0.19 - 0.69, P < 0.05).

conclusionIn this cohort, the presence of lamellated hyperintense synovitis in the MRI of hip arthroplasty showed high sensitivity and specificity for infection. This sign had substantial intra-observer reliability and moderate inter-observer reliability in the classification of the synovial pattern.
