These indicators are acceptable and are key components of the EM system but do not provide a quantitative, qualitative, and temporal trend evaluation of the progress of EM.

It would be preferable to use various trend evaluation methods [131, 132, 133, 134].
Note that the target period for HRV trend evaluation is immediately before the SIRS evaluation period.
This time trend evaluation study was based on three cross-sectional analyses of randomly selected administrative discharge records from three Swiss hospitals collected in 1999, 2001 and 2003.

For chlorpyrifos evaluation, one should recognize that a percentage of the TCPY may be also from exposure to chlorpyrifos methyl; thus, if the relative use of these two pesticides remains constant, temporal trend evaluations should be valid.
