Figure 2From: Nonlinear mixed-effects HIV dynamic models with considering left-censored measurementsViral load fit for four patients. Filled circles represent observation values; circles stand for simulated below detection limit viral load by the proposed model; Logarithm of detection limit (1.398) is represented by horizontal dotted lines; Dashed lines are viral load estimated from the model without considering censoring mechanism, while solid lines are estimated from the proposed model accounting for censoring.Back to article page
