Figure 4 Strategies employed by survey participants to treat attacks of Raynaud's phenomenon once they occur at either high or low altitude. Participants were able to report the use of multiple strategies. A list of potential strategies was provided and participants were also able to add strategies not specified on this list (N=142 respondents).
