Author contributions: Pan D and Xu L performed statistical analysis; Xu L and Zhang LX retrieved raw data from NHANES; Pan D, Shi DZ designed the study. Pan D, Shi DZ and Guo M wrote the manuscript; Xu L and Guo M acquired the fundings supporting the article. The reasons for designating Xu L and Pan D as co-first authors are as follows: First, the research was performed as a collaborative effort, the effort to retrieve raw data is necessary, and statistical analysis is also essential to finish the article. Second, the two authors cooperated together, Pan D designed the study and Xu L made effort to acquire data. Additionally, Pan D wrote the draft, and two authors managed post-submission matters. We think it is necessary for the article and the two authors contributed with equal importance. Shi DZ and Guo M were co-corresponding authors, the reasons were as follows. Shi DZ inspired the study design and checked the data from NHANES, and confirm the accuracy of the data. Moreover, Shi DZ wrote the draft for the manuscript. Guo M also wrote the draft, and responsible for the revision of the article. In addition, Guo M acquired the fundings and also maintained the raw data. Guo M and Shi DZ are responsible for the data. Hence, we thought Guo M and Shi DZ as co-corresponding authors.

ARTICLE HIGHLIGHTS
Research background

Additional research is needed to explore the underlying mechanism of the relationship between remnant cholesterol and mortality.

Research motivation

The optimal remnant cholesterol level for decreasing the risk of all-cause mortality in patients with diabetes was 0.68-1.04 mmol/L. A high level of remnant cholesterol was associated with an increased risk of all-cause and cardiovascular mortality.

Research objectives

The associations of remnant cholesterol with all-cause and cardiovascular mortality were U-shaped. Patients with diabetes in the third quartile of remnant cholesterol (0.68-1.04 mmol/L) had a lower risk of all-cause mortality, and a per standard deviation increase in remnant cholesterol was associated with a higher risk of all-cause and cardiovascular mortality.

Research methods

This cohort study included 4740 patients with diabetes who participated in the National Health and Nutrition Examination Survey from 1999 through 2018. We divided remnant cholesterol into four quartiles, and all participants were followed from the interview date until death or December 31, 2019. Multivariate proportional Cox regression models were used to calculate hazard ratios and 95% confidence intervals. Additionally, a series of subgroup and sensitivity analyses were performed.

Research results

The aim of the present study was to explore the associations of remnant cholesterol with all-cause and cardiovascular mortality in patients with diabetes.

Research conclusions

In current clinical practice, the lipid profile is different between patients with diabetes and nondiabetic patients. However, evidence for the association between remnant cholesterol levels and mortality is lacking.

Research perspectives

Remnant cholesterol is associated with mortality, but the role of remnant cholesterol in patients with diabetes is unclear.
