Censoring definitions for Li depletion events applied in our survival analysis.

Condition YiU$Y_i^U$ YiL$Y_i^L$ Censoring type Description
Li is measured and > 2.2 A(Li) A(Li) Right-censored The event has not yet occurred
Li is measured and ≤ 2.2 A(Li) A(Li) Not censored (exact) The event time is known
Li is an upper limit A(Li) -∞ Interval-censored The event has occurred but the time is uncertain
Li is missing low_li -∞ Interval-censored We assume Li depletion

Notes. The variables YiL$Y_i^L$ and YiU$Y_i^U$ represent the latent times corresponding to the lower and upper bounds of the depletion event.
