This makes a comparison between options possible.
To make a comparison between countries possible, all diagnostic codes for CM were re-coded to "clinical mastitis".
The survey was based on the survey questions used in the birth injury-project [ 19] in order to make a comparison between the projects possible.
Teat injuries were found to be less frequent in free-stalls than in tie-stalls, and this is in accordance with previous results [ 4, 7, 8] Other studies have shown poorer claw health in free-stalls [ 10- 12], but the present material did not provide sufficient information on claw health to make a comparison between housing systems possible.
In three diagnostic groupings sufficient patients (n > 100) received treatment that was not compliant with NICE to make a comparison between compliant and non-compliant therapy possible.
It is not possible to make a comparison between formulations, and information on labels and actual content may differ.
The municipality was asked to provide six matched schools and obtained four, making it possible to make a comparison between the two types of schools.
It is however possible to make a comparison between measured and modeled sewage effluent concentrations (a state variable in GWAVA that had a country resolution in this study).
Moreover, the differences x-x d have been normalized by x d in order to make a comparison between concentrations of different orders of magnitude possible.
Nor was it possible to make a comparison between the data obtained from this study and that which had emerged from research carried out in other countries because of cultural, social, economic and moral variables which enormously condition sexual behaviour.
However, we also acknowledge certain limitations of the current study: Because in the Netherlands no other protocolized psychosexual training program is available, it is not possible to make a comparison between two interventions, and therefore the control condition is a waiting-list condition.
