Recruitment at a church and other enhancements
Recruitment at a church and other enhancements may increase recruitment.
The absolute increase is 1% (95% CI = 0% to 2%)1
LOW CERTAINTY in the evidence (but see 'What we don't know' below)

The practical impact of recruitment at a church and other enhancements
Imagine a trial that needs to recruit 30 participants and initial recruitment is 30% of those approached. This means you'd need to approach 100 people to recruit 30 (see chart below).
Now imagine recruiting at a church. The chart below shows the impact of an absolute increase of 1% (95% CI =0% to 2%)1. Recruitment is now 31%, which means our best estimate is that 97 people would need to be approached to recruit 30 of them.
Where has recruitment at a church and other enhancements been tested?
Study 1: Ford 2004
African American men aged 55 to 74 eligible for a prostate, lung and colorectal cancer screening trial.
Unclear but recruitment is to cancer screening trials.
3.9% of participants randomised to receive a questionnaire were recruited; 2.9% of participants randomised to not get a questionnaire were recruited
What we still don’t know about recruitment at a church and other enhancements
- The GRADE assessment is low for this intervention because the risk of bias was unclear and there is only a single evaluation. More evaluations in any type of trial are needed.
- Please get in touch (email firstname.lastname@example.org) if you would like to do an evaluation because we can help with text for ethics etc.
