Measurement of onset time in case of an incomplete neuromuscular block (defined as T1 height did not fall <5% of baseline values): in case of an incomplete onset time was measured as the time from start of injection of rocuronium until at least 3 consecutive twitches with the same or even increasing amplitude were observed. The first of these T1 twitches served as endpoint for calculation of the onset time (red arrow and black vertical line, respectively)
