FD-2. Mean non-freeze-dried (darker bars; N) and freeze-dried (lighter bars; F) urine composition data: (a–b) Low concentration mixtures (LM), (c)–(d) High concentration mixtures (HM; Supplementary Table 1), (a) and (c) Constituents with mean concentrations over 1 g l−1, (b) and (d) Constituents with mean concentrations under 600 mg l−1. Error bars show the CI of the difference between the treatment means (N vs. F; n = 3) and are centred on the difference between the means.
