The global energy confinement time, τE, from TFTR supershot plasmas has been correlated with the hydrogen recycling and the pressure anisotropy. An expression for the global confinement is obtained that describes its value at the time of peak neutron emission for all TFTR supershots obtained in the 1990 campaign, and simultaneously describes the time evolution of τE for an extensive subset of the 1990 data. The obtained expression is probably nor unique and it can be written with different variables. An analysis of the energy balance for many of these supershots indicates that the primary effect of larger τE is that the central particle diffusivity is lower
