To maintain high data integrity, the researchers excluded pregnant or terminally ill individuals while assessing primary endpoints such as disease awareness and the percentage of patients achieving adequate blood sugar control, defined as an HbA1c level of 7% or less. • Strong Treatment Initiation: Research recorded a high treatment uptake of 88.7% among those aware, a figure superior to results from many other Indian and global cohorts. • Disappointing Clinical Control: Results demonstrate that only 52.1% of those undergoing treatment achieved adequate blood sugar control, illustrating that nearly half remain vulnerable to chronic complications. The results suggest that the "rule of halves" framework is highly applicable to diabetes mellitus because, although the prevalence reached 31.4%, only approximately 52.1% of those receiving treatment successfully maintained their blood sugar levels within the target range. Is the “rule of halves” applicable for diabetes mellitus?
