Solid markers show the invariant yields of identified particles in central (circles) and peripheral (squares) Pb-Pb collisions. Open points show the pp reference yields scaled by the average number of binary collisions for $0-5\%$ (circles) and $60-80\%$ (squares) [$Phys. Rev. C 88, 044909 (2013)$]. The statistical and systematic uncertainties are shown as vertical error bars and boxes, respectively.
