The measurement covers the transverse momentum interval $0.45 < p_{\\rm{t}} < 1.05$ GeV/$c$ and rapidity $|y| < 0.5$. The ratio is measured to be $R_{|y| < 0.5} = 0.957 \\pm 0.006 (stat.) \\pm 0.014 (syst.)$ at $0.9$ TeV and $R_{|y| < 0.5} = 0.991 \\pm 0.005 (stat.) \\pm 0.014 (syst.)$ at $7$ TeV and it is independent of both rapidity and transverse momentum.
