Table 5 Presents the results of the secondary objective of the study: the comparison of a true RDD approach to that of an opt-in approach

From: Estimation of bed net coverage indicators in Tanzania using mobile phone surveys: a comparison of sampling approaches

 

Odds Ratio [95% CI]

Household has 1 + bed net (of any type)

*1.18 [1.03, 1.36]

Household has 1 + ITN

1.06 [0.93, 1.21]

Household has 1 + bed net (of any type) per 2 de facto

***1.26 [1.12, 1.43]

Household has 1 + ITN per 2 de facto

1.06 [0.91, 1.25]

  1. RDD vs opt-in method of calling: logistic regression analysis results
  2. Each logistic regression controlled for region, radio ownership, bike ownership, and household size. In each logistic regression equation, the opt-in method was set as the reference category. Observation counts exceeded 4000 for each regression analysis
  3. RDD random digit dial; CI confidence interval; ITN insecticide-treated bed net
  4. * p < 0.05; ** p < 0.01; *** p < 0.001
