Identify the study and key findings

Using the Social Relationships and Mortality and Holt-Lunstad Meta-Analysis knowledge points
The question references a massive meta-analytic review of 148 studies over several decades. This landmark study was conducted by Julianne Holt-Lunstad and colleagues in 2010.

Determine the statistical outcome

Using the Social Relationships and Mortality and Holt-Lunstad Meta-Analysis knowledge points
The researchers found that individuals with stronger social relationships have a 50% greater likelihood of survival compared to those with weak social relationships. This effect size is comparable to quitting smoking and exceeds many other well-known risk factors for mortality.
