Start with the decision

What must this trial establish, and for whom? The required evidentiary standard determines which shortcuts are unacceptable.

Then test operational reality

Compare startup path, actual capable sites, eligible patients, competing trials, language/logistics, lab/shipping requirements and vendor support.

Price decision quality

A geography that is cheaper but slower or unable to produce interpretable evidence can have a worse Cost-to-Truth.

Questions people actually ask

FAQ

How many countries should I use?

As few as can credibly recruit the study and produce the required evidence, unless diversification adds real value.

Is faster startup enough?

No. Startup speed matters only if the sites can then enroll and produce usable data.
