Flowchart of worker recruitment and reach indicators. 1Randomization was at cluster level (hospital units were randomized). 2Participation was voluntary and free. For participatory ergonomics reach was calculated as the proportion of nursing staff who attended at least the 75% of the sessions from the number of expected participants (i.e., six workers per cluster: a volunteer nursing staff from morning, afternoon and two-night shifts, the unit supervisor/s, and one prevention delegate). For the activities targeted to overall nursing staff (i.e., Nordic walking, mindfulness and healthy diet), reach was calculated as the proportion of nursing staff who participated in these activities and attended at least the 75% of the sessions from those who signed the informed consent. Finally, for case management, reach was calculated as the proportion of nursing staff who participated in this component and attended at least the 75% of the sessions from those who the intervention was recommended (i.e., the sum of nursing staff that participated and the nursing staff that declined the intervention)
