It is unclear whether an enrolment followed a cancellation or vice versa, or whether a cancellation was intentional or the result of a computer gremlin.The 14 states that built their own exchanges seem to be faring better.
We employed multiple logistic regressions to investigate our first two research questions: (1) whether MHOs include the poor and less educated, and (2) whether MHO enrolment is associated with higher utilization of modern care and hospitalization in the event of illness.
Our study therefore cannot ascertain whether the enrolment criteria by themselves explain the results, and suggests that proning duration also played a role.
We used a log-linear regression model to investigate our third research question: whether MHO enrolment is associated with lower out-of-pocket payments for outpatient care and hospitalization.
Treatment as needed, generally resulted in less gain in VA, whether instituted at enrolment or after 1 year of monthly treatment.
Unfortunately, it is difficult to determine at the time of enrolment whether a patient really has Gram-negative infection, and one must often wait at least 48 hours for culture results.
To permit individualised care outside the study protocol, we excluded from active follow-up 290 women who had some evidence of cervical intraepithelial neoplasia grade II+ at enrolment, whether or not this was confirmed histologically by colposcopy and directed biopsies.
