IGHE and strongyloidiasis: In the multivariable analysis (n = 168), factors independently associated with confirmed strongyloidiasis were elevated IgE (OR 8.47, 95% CI 1.98–41.64; p = 0.004), hemoglobin >13.6 g/dL (OR 2.00, 95% CI 1.31–3.34; p = 0.032), and Latin American origin (OR 17.67; 95% CI 2.08–429.01; p < 0.001).
