(a) Changes in blood urea levels in earthed (A₀+B₀) and unearthed (A₁ + B₁) subjects during the first and second weeks of the experiment. (b) Changes in blood urea levels in earthed subjects in the first week of the experiment (A₀) and unearthed subjects in the second week of the experiment (A₁). *𝑃<0.001 between the groups. (c) Changes in blood urea levels in unearthed subjects (B₁) in the first week of the experiment and earthed subjects in the second week of the experiment (B₀). *𝑃<0.001 between the groups.
