To evaluate the effectiveness of different therapeutic interventions on the control of blood glucose concentration, clinical researchers monitored four cohorts of patients with Type 2 diabetes. The blood glucose concentrations of the cohorts, recorded 2 hours post-therapy, were represented in the format mean±standard deviation\text{mean} \pm \text{standard deviation}mean±standard deviation as follows:

  • Cohort P: 5.7±0.9 mmol dm−35.7 \pm 0.9\text{ mmol dm}^{-3}5.7±0.9 mmol dm−3
  • Cohort Q: 6.4±1.2 mmol dm−36.4 \pm 1.2\text{ mmol dm}^{-3}6.4±1.2 mmol dm−3
  • Cohort R: 5.2±0.3 mmol dm−35.2 \pm 0.3\text{ mmol dm}^{-3}5.2±0.3 mmol dm−3
  • Cohort S: 6.1±0.7 mmol dm−36.1 \pm 0.7\text{ mmol dm}^{-3}6.1±0.7 mmol dm−3

Identify which cohort's post-therapy blood glucose concentration measurement is the most precise, and explain your choice.
