Risk Ratio Between Unsafe Injection and NBT for HIV after Adjusting for Measured and Unmeasured Confounders

Risk Ratio 95% Confidence/Credible Interval
Unsafe injection 0.96a 0.89–1.03b
Adjusted unsafe injection Bias analysis 1 (expert 1) 0.95c 0.84–1.08d
Adjusted unsafe injection Bias analysis 2 (expert 2) 0.82e 0.64–0.99d
a

Risk Ratio adjusted for the measured confounders (age, gender, education, history of imprisonment at baseline and 3-month follow-up and ever tested for HIV at baseline).

b

95% Confidence Interval.

c

Risk Ratio adjusted for measured confounders (age, gender, education, history of imprisonment at baseline and 3-month follow-up and ever tested for HIV at baseline) and unmeasured confounder (insufficient knowledge) based on the first expert’s priors.

d

95% Credible Interval.

e

Risk Ratio adjusted for measured confounders (age, gender, education, history of imprisonment at baseline and 3-month follow-up and ever tested for HIV at baseline) and unmeasured confounder (insufficient knowledge) based on the second expert’s priors.
