Table 3 Household response proportions

From: The use of incentives in vulnerable populations for a telephone survey: a randomized controlled trial

  Incentive Group Non-Incentive Group Between Group Difference (95% Confidence Interval)
Response Rate 36.1% (n=277) 28.7% (n=272) 7.4% (−0.7%, 15.6%)
Cooperation Rate 44.6% (n=224) 36.6% (n=213) 8.2% (−1.6%, 17.7%)
Less Conservative Cooperation Rate 58.5% (n=224) 52.1% (n=213) 6.4% (−3.4%, 16.1%)
  1. n refers to the denominator. The response rate n is larger due to the inclusion of non-contacts.
