Given a passage classify if the passage has a definite objective/aim/goal or not. Output '1' if the passage has a defininte objective/aim/goal and output '0' if the passage does not have a definite objective/aim/goal.

To know whether metformin improves postprandial hyperglycaemia, we examined the effect of metformin on the glycated albumin (GA) to glycated haemoglobin (HbA1c) ratio (GA/HbA1c ratio) in patients with newly diagnosed type 2 diabetes.', 'Metformin and lifestyle interventions were initiated in 18 patients with newly diagnosed type 2 diabetes. Metformin was titrated to 1500 mg/day or maximum-tolerated dose. HbA1c and GA were measured every four weeks up to 24 weeks.', 'HbA1c decreased significantly from 9.0 2.1% at baseline to 6.5 0.9% at week 24, and GA decreased significantly from 24.3 8.2% to 16.2 3.1%. The GA/HbA1c ratio decreased significantly from 2.66 0.37 at baseline to 2.47 0.29 at week 24 (P<0.01), despite that the GA/HbA1c ratio reached a plateau value at week 16. The change in the GA/HbA1c ratio during 24 weeks (GA/HbA1c ratio) was significantly correlated with both baseline HbA1c and GA. Moreover, the GA/HbA1c ratio was significantly correlated with the change in GA during 24 weeks but not with the change in HbA1c.
