"entries" field is often 0

On a time profiling report the "entries" field is often
zero.
If I want to know why "getAppropriatePreds" takes up so
much time (14.7%) in my code, does the zero mean an
overflowed count or that the cost centre has never been
entered? I'm using 5.04.2 on Linux, and my program is
compiled with -O -prof -auto-all.
 
For example:

   compose         InfrequentCheck   1137    12280580 
 2.1    2.5   2.1    2.5
  align            InfrequentCheck   1127           0 
 3.7     6.2     8.3      6.7
   align2          InfrequentCheck   1139     8577943 
 0.4    0.0  0.4    0.0
   lookupModeArgs  InfrequentCheck   1136    86747940 
 4.2    0.4  4.2    0.4
   getAppropriatePreds InfrequentCheck  1126        0 
14.7    6.6  14.7    6.6
