Published: September 2022

The variance-stabilizing Freeman-Tukey double arcsine transform was originally proposed for inference on single proportions. Subsequently, its use has been suggested in the context of meta-analysis of proportions. While some erratic behavior has been observed previously, here we point out and illustrate general issues of monotonicity and invertibility that make this transform unsuitable for meta-analysis purposes.

Introduction: Although the prevalence of chemotherapy-induced peripheral neuropathy (CIPN) has been reported, the proportion of patients with CIPN who report chronic painful neuropathy remains poorly understood, despite its significant impact on patients' quality of life and treatment outcomes.

Methods: A systematic review and meta-analysis were conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The primary outcome was the pooled prevalence of chronic (≥3 months) painful CIPN among patients diagnosed with CIPN.

Background: Children with one functional ventricle might receive the Fontan procedure as palliative management to prolong their lives. However, the heart remains functionally univentricular, which may result in disrupted absorption of nutrients, including Vitamin D. Individuals with Fontan circulation have limited physical activity and sun exposure, which might further contribute to Vitamin D deficiency.

Background: Removal of cardiac implantable electronic devices (CIEDs) is strongly recommended for CIED-related infections, and leadless pacemakers (LPs) are increasingly used for reimplantation. However, the optimal timing and safety of LP implantation after CIED removal for infection remains unclear.This systematic review and meta-analysis aimed to assess complication rates (all-cause mortality and reinfection) when LP implantation was performed simultaneously with or after CIED removal.
