Limitations and Caveats
Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
Insufficient time period used to be able to establish a substantive therapeutic effect of rTMS; standard dosing method may be inadequate due to volumetric changes in brain regions in schizophrenia; concurrent antipsychotic medication.
