Health impact estimations depend on baseline prevalence of active travel participation, baseline exposure to health pathways and the general status of the population".
The photographs were graded by an experienced ophthalmologist [EA], blinded to baseline exposure status, using the International Clinical Diabetic Retinopathy Disease Severity Scale [67].
In order to consider any potential changes in the Ca2+ concentration between the baseline, exposure and washout periods that might be attributable to the GSM exposure, a mixed model repeated measures analysis of variance was performed.
Statin baseline exposure was defined using three approaches.
However, cut-offs would differ based on baseline exposure to SHS.
These cut-offs would also differ according to baseline exposure to second-hand smoke (SHS).
Abuse was prevalent among WHI participants, with 11%% of our study population reporting baseline exposure.
The baseline, exposure and recovery periods are indicated in Fig. 1.
Following this approach, a subcohort of 2,589 women was sampled after the baseline exposure measurement.
Baseline exposure, however, was a good proxy of drug use during subsequent follow-up.
