Can cog thread lift end up with no result?

Yes, it is certainly possible that no result was obtained.  There can be a number of reasons for this including:
1.  Your tissues are not mobile enought
2.  Not enough threads placed
3.  Threads not sufficiently anchored
4.  Thread type is too weak
5.  Thread angles not ideal
6.  Too much motion in your face after thread placement
Usually adding threads can improve results.  But, sometimes they simply don't work well.
