Hello all,

I am using Stata 16.0.

I am working on a systematic review in which I have many predictors (ex. coma, lethargic, pallor) from different studies to predict severe outcome (ex. death). We extracted the 2x2 table data (variables A B C D) and calculated the likelihood ratios (variables: PLR NLR) for each predictor (variables: predictor).

So the data looks like this
Study Predictor A B C D PLR NLR
xxx Coma 5 8 6 8 xx xx
xxx Pallor 3 6 35 44 xx xx
xxx Convulsions 55 66 77 88 xx xx
A= true positive, B = false positive, C= False negative, D= True negative, PLR: Positive likelihood ratio, NLR: Negative likelihood ratio

How can I generate the confidence intervals for each predictor (generate a new collumn with the upper and lower 95%CI for both the PLR and NLR?

I have tried to play around with commands such as diagt and metandi but I am unable to figure out how to generate the confidence intervals.

Any help would be very appreciated.

Thanks,

Rainer
