Figure 6

Boxplots of time taken by astronauts depending on steps (a). Center line: median, box limits: upper and lower quartiles, whiskers: 1.5 × interquartile range, °: outliers, Min: minutes, *: p < 0.05, ****: p < 0.0001 from one-way ANOVA test. Graphs of absolute and relative means of time for each stacked step depending on groups (surgical control or astronauts) (b). Dotted grey lines (…): lines connecting steps between both groups suggesting a difference when lines are not parallel between lower and upper border of a step or a similarity if both lines are parallel. Min: minutes, ns: non-significant. Strip chart of time required for each step depending on educational background (c). The different educational background between astronauts did not affect neither the total time (p = 0.904) nor the time at each step (p = 0.396, p = 0.961, p = 0.669, p = 0.340 from step 1 to 4 respectively) following the one-way ANOVA test. Min: minutes. Bars: medians.
