ALICE results displayed in terms of spin density matrix elements, along with statistical and systematic uncertainties. A comparison with the available lowest $Q^2$ ranges of the results from the H1 and ZEUS collaborations is also provided. H1 results  correspond to $Q^2 \sim 0.05$ GeV$^2$ consistent with photoproduction, while the shown ZEUS measurement  is for $2 < Q^2 < 5$ GeV$^2$.
