Table 3 Difference in yield of screening in asylum seekers from countries depending on the WHO-estimated incidence of TB in their country of origin, adjusted for age, sex, and period-effects, 2002–2015, Germany, N = 116,813

From: Using country of origin to inform targeted tuberculosis screening in asylum seekers: a modelling study of screening data in a German federal state, 2002–2015

Predictor Rate Ratio (95% CrI)
Country of origin with a WHO-estimated high incidence of TB (> 50 per 100,000) (Reference: Country of origin with a WHO-estimated low and intermediate incidence of TB (≤ 50 per 100,000)). 4.17 (2.86, 6.59)
Age (years) 1.02 (1.00, 1.03)
Female (vs. male) 0.44 (0.26, 0.72)
Period (Reference: 2002–2012)
 2013 0.43 (0.20, 0.83)
 2014 0.96 (0.62, 1,49)
 2015 0.69 (0.44, 1.1)
  1. CrI credible interval, TB tuberculosis. Difference in observations to N = 119,037 are due to a complete case analysis and missing data for country of origin (n = 2042), age (n = 88), sex (114). Bold figures: 95% CrI larger or smaller than 1
