Thus far, the pathophysiological mechanism to develop a XXX is not yet fully understood.

[John012]

Some questions:

1 This may be interpreted as follows/following: ?
2 One limitation is the use of a retrospective study design per se (is per se right? or "itself" or any other suggestions?)

3 Which one sounds the best?: A,B or C?
A) Thus far, the pathophysiological mechanism to develop a XXX is not yet fully understood.
B) Thus far, the pathophysiological process behind XXX and the YYY system is not yet fully understood.
C) The pathophysiological processes behind XXX and the YYY system remain unclear.

Thanks!

Thanks,
3 - it's more about the expression: remain unclear or not yet fully understood

Another Question:

In comparison with this present study, a ratio of approximately 10 : 0.9 can be seen.

Is "can be seen" correct here?
