Before work, the IKI population had significantly higher urinary citrate ( P < 0.001, BH‐adjusted P = 0.008), and showed an observed trend ( P < 0.05, but BH‐adjusted P ≥ 0.05) toward higher 4‐hydroxybenzoate ( P = 0.009), and acetone ( P = 0.01) levels compared to the non‐IKI population (Figure 2 ; Table 3 ).
