  1. For both Shapiro-Wilk and Kolmogorov-Smirnov tests, W indicates the associated test statistic, whilst the p-value indicates the significance of this statistic. Those highlighted in bold and italicised are significant at 5%, indicative of a normal distribution. Raw data may be found in Tables SI 1–3.
  2. *Insufficient data points for Kolmogorov-Smirnov test.
