Despite technological advances, the survival records from longevity experiments
remain the most indispensable tool in ageing-related research. A variety of
interventions, including medications, genetic manipulations and calorie
restriction (CR), have been demonstrated to extend the lifespan of several
species. Surprisingly, few systematic studies have investigated the differences
among these anti-ageing strategies using survival data. Here, we conduct a
comprehensive and comparative meta-analysis of numerous published studies on
Caenorhabditis elegans and Drosophila. We found that CR and genetic manipulations
are generally more effective than medications at extending the total lifespan in
both models, and CR can improve the ageing pattern of C. elegans. We further
analysed the survival variation for different anti-ageing medications and
determined that hypoglycaemic agents and antioxidants are advantageous despite
only moderately increasing the overall lifespan; therefore, these two types of
medications are promising CR mimetics. Analysis of genetic manipulations also
indicated that the genes or pathways that extend lifespan in a healthier pattern
are associated with CR. These results suggest that CR or CR mimetics may be the
most reasonable and potentially beneficial anti-ageing strategy.
