Participants were asked to rate the following statement, “Animal-based research should be phased out only if …”, completed with a set of different options regarding the gaps or barriers to overcome for phasing out animal experimentation. Rating scale was from 1 (red) to 5 (dark green) stars. Histogram dimensions are represented as 100%, where 100% is the total number of participants of each subgroup: human-based (39), animal-based (30) and both (44) model users. The stacked chart, calibrated around the neutral score (in grey, 3 stars), shows the number of respondents based on their degree of agreement and segmented by researchers’ use of animal- or human-based or both models.
