What this study reported

Reported higher serum MOTS-c and thiobarbituric acid reactive substances in patients with acute coronary syndrome than in controls, with a positive correlation between the two. Found that the ratio of MOTS-c to thiobarbituric acid reactive substances discriminated patients who went on to have major adverse cardiac events over 18 months of follow-up in the acute myocardial infarction group. Reported in cultured cells that oxidative stress raised MOTS-c levels and that MOTS-c exposure lowered hypoxia-induced oxidative stress.

Limitations

Single-timepoint admission sampling in one recruited cohort with no external validation of the reported cut-off values, modest discrimination statistics, and in vitro work in an unspecified cell system reported only in summary.

Appraisal

Each dimension is recorded separately and never combined into a single score. A study can be well controlled and still tell you little about people.
