Short-Term Radiographic Outcomes of Bone Versus Metallic Augmented, Central Screw Type Baseplate in Reverse Total Shoulder Arthroplasty: Matched Case-Control Study.

Background: Although glenoid bone grafting and metallic augmented baseplates have demonstrated success in restoring the glenohumeral joint line in the recent literature, there remain no consensus guidelines defining the use of one versus the other.

Methods: Between 2017 and 2020, 15 primary RTSA with screw-in metallically augmented glenoid baseplates were identified and 2:1 matched by age, sex, and body mass index with primary bony-augmented glenoid baseplate patients. Patients with previous glenoid implantation or fracture were excluded.

The Problem With Predicting Uncommon Events: The Critical Effect of Prevalence in Test Performance.

We used the Bayesian model to show the relationship between prevalence and the test's negative and positive predictive value. We used the above principle to understand the utility of biomarkers for acute rejection under different pretest probability of rejection. Given the test's sensitivity and specificity, the disease prevalence affects the predictive value of the test; the clinical decision to get any test should be considered while understanding the prevalence of disease and cost, risks, benefits of the tests, and available alternatives.

Current State of Evidence on Kidney Transplantation: How Fragile Are the Results?

Background: The study aims is to use the fragility index (FI) to examine the strength of evidence of randomized controlled trials (RCTs) published in the last decade on kidney transplantation.

Methods: We searched MEDLINE for studies on kidney transplantation. We included the RCTs that compared 2 groups with 1:1 randomization and reported significant P values (<0.
