N2 - The [CII] 158 mu m line is one of the strongest IR emission lines, which has been shown to trace the star formation rate (SFR) of galaxies in the nearby Universe, and up to z similar to 2. Whether this is also the case at higher redshift and in the early Universe remains debated. The ALPINE survey, which targeted 118 star-forming galaxies at 4.4 6 [CII] measurements (detections and upper limits) do not behave very differently to the z similar to 4-6 data. We find a weak dependence of L([CII])/SFR on the Ly alpha equivalent width. Finally, we find that the ratio L([CII])/L-IR similar to (1-3) x 10(-3) for the ALPINE sources, comparable to that of "normal" galaxies at lower redshift. Our analysis, which includes the largest sample (similar to 150 galaxies) of [CII] measurements at z>4 available so far, suggests no or little evolution of the [CII]-SFR relation over the last 13 Gyr of cosmic time.
