LTC3883 EEPROM Retention

The LTC3883 gives the minimum EEPROM retention at 10 years if Tj < 125 deg.C, but does not give data for lower temperatures.

The datasheet also gives a de-rating equation for Tj > 125, but I'm interested in the data retention time for Tj <125.

Can you provide an equation or chart for minimum EEPROM retention as a function of Tj for < 125 deg.C?
