Fig. 2From: Evaluation of time to reimplantation as a risk factor in two-stage revision with static spacers for periprosthetic knee joint infectionIdentification of the optimal cutoff point for the time to reimplantation regarding reinfection-free survival after the second stage in a two-stage exchange arthroplasty of the knee. The optimal cutoff was identified using the maximally selected log-rank statistic as proposed by Hothorn and Lausen [25] and implemented in the R maxstat package [26]Back to article page
