Effects of the number of food and sleep patches on average sleep time. Average number of sleep minutes when the number of food patches equals the number of sleep patches. Values on the x-axis are the sum of food and sleep patches (e.g., 80 refers to 40 food patches and 40 sleep patches): interDistance 0.0: r _S = 0.86, N = 104, P < 0.001; interDistance 0.35: r _S = 0.74, N = 100, P < 0.001; interDistance 0.7: r _S = 0.61, N = 84, P < 0.001.
