Lack of an association or an inverse association between low-density-lipoprotein cholesterol and mortalityin the elderly: a systematic review

*This is the first systematic review of cohortstudies where low-density lipoprotein cholesterol(LDL-C) has been analysed as a risk factor forall-cause and/or cardiovascular mortality inelderly people. 

Lack of an association or an inverse associationbetween LDL-C and mortality was present in allstudies.

 We may not have included studies where an evaluation of LDL-C as a risk factor for mortality was performed but where it was not mentioned in the title or in the abstract. 

We may have overlooked relevant studies because we have only searched PubMed. 

Minor errors may be present because some of the authors may not have adjusted LDL-C by appropriate risk factors. 

Some of the participants with high LDL-C may have started statin treatment during the observation period and, in this way, may have added a longer life to the group with high LDL-C and some of them may have started with a diet able to influence the risk of mortality.

 We may have overlooked a small number of relevant studies because we only searched papers in English.
