Abstract

Objective: This study aimed to compare the effects of empagliflozin-metformin versus empagliflozin- linagliptin combination

therapy on cardiovascular parameters and anemia in patients with type 2 diabetes mellitus (T2DM).

Study Design and setting: An analytical study was conducted over 12 weeks at National Medical Centre Hospital, Karachi.

Methodology: T2DM patients were randomly assigned to either the Empagliflozin 12. 5 mg with Metformin 500mg or

Empagliflozin 10mg with Linagliptin 5mg. Clinical assessments were conducted at baseline Week 0, 4, and 12, focusing

on C-reactive protein levels, blood pressure, temperature, heart rate, respiratory rate, ECG findings, hemoglobin levels,

BMI, and glycated hemoglobin (HbA1c) and cardiac examination was performed in all visits. Descriptive statistics were

used to compare outcomes between the groups.

Results: The comparative analysis of empagliflozin–metformin (EM) and empagliflozin–linagliptin (EL) regimens

demonstrated notable differences in outcomes. HbA1c decreased significantly in both groups, but the EL group showed a

greater reduction by week 12 (p = 0.021, OR = 1.65, 95% CI: 1.05–2.58). BMI declined in both arms, but intergroup difference

was not statistically significant (p = 0.078). CRP levels dropped more in the EL group, reaching statistical significance (p

= 0.037, OR = 1.43, 95% CI: 1.01–2.11). Cardiovascular parameters, including systolic BP (p = 0.116) and diastolic BP

(p = 0.098), remained stable, showing no…

How strong is the evidence?

Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design.
