Hello All,

All else equal, would it be more desirable to have (A) 40 studies each
with two estimates of effect size or (B) 20 studies each with 4
estimates of effect size?

My intuition is that (A) is more desirable than (B).

Would it also be more desirable to have (C) 80 studies each with 1
estimate of effect size over (A) and (B)?

ps. By "desirable" I mean higher generalizability to the target population.

Thank you,
