Figure 5.

The relation between consecutive clusters of self-reported cycling durations and the estimated cycling velocities for males (mean value and 80% confidence interval) (n = 498). The even-numbered clusters represent durations with the last digits being 0 or 5 (red symbols connected with continuous lines). The uneven-numbered clusters represent durations with the last digits being 1–4 or 6–9 (blue symbols connected with dashed lines). For further explanations, see legend to Figure 4 and Methods.
