We reexamine the quark-lepton complementarity (QLC) in nine angle-phase parametrizations with the latest result for a large lepton mixing angle $\vartheta_{13}$ from the T2K, MINOS and Double Chooz experiments. We find that the original form of the QLC two relations only hold in the standard parametrization (P1) and only one of the relations holds in P2, P3, P4, P5, P6 and P9 parametrizations separately. We also work out the corresponding reparametrization-invariant form of the relations and examine the resulting expressions with the data. The results can be used as check of the validity of the QLC relations, as well as new perspective into the issue of seeking the connection between quarks and leptons.
