Lock the essentials,
rebuild only the wording

Numbers, units, formulas, citations, terminology and the strength of a claim are kept exactly as they were. Only the phrasing is rebuilt naturally, without introducing deliberate typos or grammar errors to fool detectors.

Across both cohorts the treated group significantly outperforms the control, r = 0.62, p < .001, consistent with (Smith et al., 2021). Substituting the calibration constant k0 into

Cth = k0 · A1 − e−λt(4)

yields a threshold of 12.4 mg/L2, plotted in Fig. 3 and tabulated in Table 12.
