Deflected succession - caused by human interaction - leads to a plagioclimax community. The community stopped developing due to human interaction, it is at a stable state. Such as mowing grass, so the patch of land remains as grass.
A subclimax community is before the climax community - final stage in succession.
Just as an extra:
You have primary succession and secondary succession
Primary - succession starts on new area/ exposed area of environment (such as on land)
secondary - a disturbance (flood, fire) kills a community, but soil and nutrients remain, than succession begins again (but is faster than primary).
