Please explain these results, specifically explain the meaning of the overall relative risk of 2.32 and why is significant.

Seven randomized controlled trials (RCTs) reported the outcome of achieving 5% weight loss in adults with overweight or obesity (Kuller et al 2012, Weinhold et al 2015, Huseinovic et al 2016, Siddiqui et al 2017, Johnson et al 2019, Ma et al 2019, Rollo et al 2020). All studies reported data that could be pooled in meta-analysis. Participants receiving nutrition and physical activity interventions had a relative risk (RR) (95% CI) of 2.32 (1.64, 3.29) (p Studies Estimate (95% C.I.)
