Table 2.

Homeostasis effect on HbA1c measured at baseline and after 6 months of intervention, Group of PPS-reverters compared to group of non-reverters, and for three groups of participants based on baseline HbA1c; Group A) HbA1c < 53 mmol/mol; Group B) 53 mmol/mol ≤ HbA1c < 64 mmol/mol; Group C) HbA1c ≥ 64 mmol/mol).

HbA1c: [mean (SD)] mmol/mol	n	Baseline	Post treatment	Between group P-value (post-treatment)	Cohen's effect size
Group A: Baseline HbA1c<53 mmol/mol
PPS reverters	28	47.4 (3.3)	46.3 (4.2)	0.1	0.6
PPS non-reverters	35	47.3 (3.3)	48.6 (6.5)
Group B: 64 mmol/mol > HbA1c ≥53 mmol/mol
PPS reverters	13	55.6 (2.2)	50.5 (5.4)	0.016	3.0
PPS non-reverters	17	56.2 (3.1)	56.4 (6.9)
Group C: HbA1c ≥64 mmol/mol
PPS reverters	11	73.2 (7.6)	58.6 (8.6)	0.01	14.6
PPS non-reverters	8	69.9 (4.2)	71.4 (10.2)
