earlier/early on

[dean]

Hi all,
Please somebody help me with my English?

It is not justified generalizing this study because of some disadvantages of this study as mentioned early on (earlier?). Besides that, this study was done in H which may has different trend of advertising compare to A and M. This study surveyed leaflet and insert different from my propose sample which is pharmaceutical advertising in medical journals. There was no information if the data were dual-inputted and verified before being accepted into the database.

Thanks,
dean

Generalising this study is not justified because of the issues/problems (I'm not taken with disadvantages) mentioned above (or earlier), besides which, the study was carried out in H, which may have different advertising trends from A and M. This study surveyed leaflet and inserts different from my proposed sample, which is pharmaceutical advertising in medical journals. There was no information if the data were dual-inputted and verified before being accepted into (I'd use 'in) the database.
