Description of selected mathematical modeling studies.

S susceptibles compartment; force of infection; reactivation rate; HZ herpes zoster; PDE partial differential equations; WAIFW who-acquires-infection-from-whom; CP chickenpox; R CP recovered compartment; Sboost susceptible to boosting compartment; ODE ordinary differential equations. *H = High: the quality of methods used in this paper permits the results, within the scope of the study design, to be interpreted with at the most a few remarks. M = Medium: the quality of methods used in this paper permits the results, within the scope of the study design, to be interpreted, but with some caution. L = Low: the quality of methods used in this paper urges the reader to interpret the results, even within the scope of the study design, with sufficient caution. £See Table S2. **The ‘B’ statement expresses whether the study supported the existence of exogenous boosting (‘+) or not (‘−’).
