This is compounded due to the limitation within our data collection which did not include disease activity at the time of iron treatment and hence we are unable to distinguish clearly between patients with active disease and those in remission.
The limitations of this study include the retrospective design and data collection, which did not allow us to evaluate some potentially useful variables such as PSA-velocity, PCA3, treatment outcomes, and survival information; and our study cohort might be subject to selection and recall bias.
One such gap is due to a limited approach to data collection and analysis which does not give adequate consideration to the needs of women with differing chronic health conditions, or the breadth and diversity of chronic health conditions which may benefit from preconception health services.
Modern geotechnical numerical design is limited by conventional characterization and data collection practices, which do not capture detailed parameters of intact rock and rockmass structure that are necessary for input to sophisticated and powerful simulation tools.
The main reason was the instability of the political situation during the data collection time, which did not allow for a more representative selection of sample.
Research data are gleaned from data recorded by various providers in the system, which does not allow for standardized collection, grading, and documentation of the data.
This data collection setup allows a fully automatic experiment control which does not require operator intervention.
We drew on a range of previous studies [ 9- 12]: ethical approval was gained from the local research ethics committee for the collection of data which did not fall within the remit of service evaluation.
Data loss was a problem with older magnetometer data collection systems like CANOPUS, which did not use local data storage (Mann et al. 2008).
Also, we show that fraction collection times, which do not divide the GnRH pulse period evenly, lead to irregularities in the data.
