Given the observational design, it was not possible to standardized the timing and method of measuring IOP levels and visual field defects.
Since propagation delays are distance dependent through, where is the speed of light, the observed timing reference of measured at different UTs, denoted, are mutually different.
We find that considerable heterogeneity in the timing of measures is necessary for multi-species conservation.
Thus the analysis of the paper allows deriving clear policy implications concerning the choice of action, and in particular the timing of measures to be taken by policy-makers if a financial crisis may be looming in the future.
Table 1 summarises timing of measures, described in more detail below.
Individuals were treated as level-two units and the timing of measures as level-one units.
The timing of measures varied, with some studies measuring a screening indicator within a one year period and others measuring over a longer period of time.
Although the results have been inconsistent, differences in the exposure matrices, timing of measures of thyroid hormones, PCB congeners measured, and statistical methods make direct comparisons difficult.
