Trial report in Diabetic medicine : a journal of the British Diabetic Association, 2011. The graph read 2 numbers from its abstract, feeding 1 cell of the map, but it casts no vote: it is a later paper about NCT00518882, whose primary report (PMID 19515413) speaks for the trial. It reports registered trial NCT00518882. Cited by 13 papers, 1 of them a synthesis that pooled it.

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

Abstract

The marked sentences are the ones the graph read a number from.

aimsThe Liraglutide Effect and Action in Diabetes 6 trial was an open-label trial comparing liraglutide with exenatide as an 'add-on' to metformin and/or sulphonylurea.

methodsPatients with Type 2 diabetes were randomized to liraglutide 1.8 mg once daily or exenatide 10 μg twice daily for 26 weeks. This was followed by a 14-week extension phase, in which all patients received liraglutide 1.8 mg once daily.

resultsPatient-reported outcomes were measured in 379 patients using Diabetes Treatment Satisfaction Questionnaire status (DTSQs) and DTSQ change (DTSQc). The change in overall treatment satisfaction (DTSQs score) from baseline at week 26 with liraglutide was 4.71 and with exentaide was 1.66 [difference between groups 3.04 (95% CI 1.73-4.35), P<0.0001]. Five of the six items on the DTSQs improved significantly more with liraglutide than with exenatide (differences: current treatment 0.37, P=0.0093; convenience 0.68, P<0.0001; flexibility 0.57, P=0.0002; recommend 0.49, P=0.0003; continue 0.66, P=0.0001). Patients perceived a greater reduction in hypoglycaemia at week 26 with liraglutide than with exenatide [difference in DTSQc score 0.48 (0.08-0.89), P=0.0193] and a greater reduction in perceived hyperglycaemia [difference 0.74 (0.31-1.17), P=0.0007]. During the extension phase, when all patients received liraglutide, DTSQs scores remained stable in patients who continued on liraglutide and increased significantly (P=0.0026) in those switching from exenatide.

conclusionsThese results demonstrate significant improvements in patients' treatment satisfaction with liraglutide compared with exenatide.
