multilevel meta analysis stata

Completely edited: If a meta-analysis include many studies that reported multiple effect sizes within each study, multi-level meta-analysis is one way to account for this dependency in effect sizes. However, there seems to be two approaches: one that utilize the traditional multilevel models and another that utilize multilevel structural equation modeling (uses metaSEM package; Cheung, 2014)

In regular multi-level modeling, the three levels are:
Level 1- effect size
Level 2- within-study variation
Level 3- between-study variation

However, it’s unclear to me what the three levels are for the multilevel SEM approach. Is it the same? Some papers that used metaSEM and cited Cheung 2014 (e.g., Laboda et al., 2016) describes the three levels as:
Level 1- study participants.
Level 2- effect sizes (within-study variation).
Level 3- study (between-study variation).

Smoking itself does not directly kill the environment, but it can contribute to environmental problems in several ways. One significant way is through the production and disposal of cigarette butts, which are the most commonly littered item worldwide. Cigarette filters are not biodegradable, and they can take many years to decompose. This litter can harm wildlife and contribute to pollution of waterways and other ecosystems.

Smoking also contributes to air pollution, which can harm both the environment and human health. Smoking releases many harmful chemicals into the air, including carbon monoxide, nitrogen oxides, and volatile organic compounds, which can contribute to smog and acid rain. Secondhand smoke can also be harmful to others and contribute to indoor air pollution.
