Table 1

Comprehension and retention of key informed consent messages at 4, 24 and 52 weeks follow-up, MDP301 Trial, Mwanza1

Message

N (%) of participants with accurate message retention at each visit

Chi square test for linear trend, 4 to 52 weeks (p-value)


Wk 4 (n = 99)

Wk 24 (n = 83)

Wk 52 (n = 74)

All wks combined (N = 256)


Key message 1:

Gel may not protect her from HIV

76 (76.8%)

59 (71.1%)

62 (83.8%)

197 (77.0%)

0.90 (p = 0.341)


Key message 2:

Condoms will protect her from HIV

82 (82.8%)

69 (83.1%)

59 (79.7%)

210 (82.0%)

0.25 (p = 0.619)


Key message 3:

She will have to stop using gel if she becomes pregnant

92 (92.9%)

78 (94.0%)

69 (93.3%) §

239 (93.3%)

0.19 (p = 0.665)


1A single researcher made an assessment of message retention at each time point; it was therefore not possible to calculate a Kappa statistic for concordance

§ There was one missing value at wk 52
