To assess the efficacy of a novel interim intervention technique using retrospective, blinded, professional continuous glucose monitoring system (pro CGM) with the Freestyle Libre Pro system over a 14-day single sensor wear-period. A retrospective analysis comprised of 105 consecutive adults at single centre in India with Type 2 diabetes, HbA1c > 53 mmol/mol (>7%), on non-insulin divabetes agents and/or insulin. The interim intervention technique included three visits over 14 days: Visit 1, sensor placed and patients asked to keep a food log while on pro-CGM; Visit 2 (within 1 week), interim assessment of pro CGM and diet or pharmacotherapy modifications made accordingly; Visit 3 at day 14, pro CGM re-evaluated to assess glycemic control. Glucose target range was set at 70–180 mg/dL. Analyses included pre & post daily average glucose, time in range, time above range, and time below range. Average time for interim analysis was 5 days after pro CGM initiation. At Visit 3, daily average glucose decreased from 191.3 mg/dL at baseline to 137.4 mg/dL (p
