evidence: The cumulative incidence of T2DM was significantly lower in the ILG than UCG among participants with baseline HbA1c levels ≥5.7% (log-rank=3.52, p=0.06; Breslow=4.05, p=0.04; Tarone-Ware=3.79, p=0.05), while this was not found among participants with baseline HbA1c levels <5.7% (log-rank=0.31, p=0.58; Breslow=0.56, p=0.46; Tarone-Ware=0.43, p=0.51; figure 2).
intervention: intensive lifestyle intervention group (ILG)
comparator: usual care group (UCG)
outcome: 2 h plasma glucose and the glucose the area under the curve (AUC) - among participants with baseline HbA1c≥5.7%
