Figure 4

Graph of breathing frequency. Graph to show the difference in breathing frequency between the two environments over time. Each data point represents data obtained from a study and the number refers to the time point. If the data point is in the green area, the breathing frequency was found to be higher in HH but if in the blue area, the breathing frequency was found to be lower in HH.
