xcode instruments leak check interpretation

Does anyone know how I interpret this allocation summary from the xcode instruments leak check. Does "Persistent" mean that those bytes are leaking?

Category | #Persistant | Persistent Bytes| #Transient| Total Bytes| # Total
--------------------------------------------------------------------------------------
All Head Allocations |6 |384 Bytes |5 |2.59KiB | 11
Malloc 80 Bytes |3 |240 Bytes |0 |240 Bytes | 3
Malloc 40 Bytes |3 |144 Bytes |0 |144 Bytes | 3

Thank you in advance
