Methods of meta-analysing linear regression data

Hello,

I am looking at the association between levels of anxiety (low, moderate, significant vs no anxiety) and blood pressure readings in several cohort studies.

I have run linear regression models in each of my three cohorts generating the results in this format;
(NB this is not my data, it is an example set from the stata webpage)

Source | SS df MS Number of obs = 200
-------------+------------------------------ F( 4, 195) = 46.69
Model | 9543.72074 4 2385.93019 Prob > F = 0.0000
Residual | 9963.77926 195 51.0963039 R-squared = 0.4892
Total | 19507.5 199 98.0276382 Root MSE = 7.1482

What methods are there for meta-analysing the results in the three cohorts? Is there a standard way of doing this in stata? I am having trouble understanding what information, alongside the coefficient, should be included (I am new to stats, apologies if this is a very basic question!)
