- FIGURE 1.
Graphic depicting each patient population in this study and subgroups within each population.
- FIGURE 2.
Wireless (left) and nonattenuating (right) call devices used in this study.
- FIGURE 3.
Cumulative percentages of positive, neutral, and negative responses for each survey question.
- FIGURE 4.
Contour map of Spearman coefficients for all pairs of questions. This visual representation of correlation coefficients between questions in first population of patients is given as simple reference to show high-correlation questions vs. low-correlation questions.
- FIGURE 5.
Box plots for groups 1–3 from patient population 2 showing unexpected result that patients who were told of device before procedure experienced greater anxiety.
- FIGURE 6.
Box plots for patient population 3 showing significant decrease in measured anxiety and narrowing of inner quartile ranges with call device.
