Can I include under-review content in my PhD Thesis? In the verge of writing up a PhD thesis, is it fine to include the content of the work which is submitted to a conference and is "under review" at the time of writing up. More specifically if the conference has 'double-blind' review process.Or is it advisable to wait till the review decision on publication is out. 

Please suggest.

Thanks, KR
I am sure this may vary but this is standard procedure for our theses since they are based on papers. A student will typically have about four papers/manuscripts in their thesis ranging from published through all stages of revision in a journal to not yet submitted manuscripts. 

You will need to check with your local guidelines what is expected from a thesis to figure out the details but it would seem difficult to demand all published papers unless the period to complete a PhD is open ended.
