Why do you think your paper is highly
cited?
The topic is very important for clinicians. There is a heated debate
whether second-generation antipsychotic drugs differ in efficacy. We found
that there are some differences. This also challenges a psychiatric dogma
that all antipsychotic drugs are equally efficacious.
Does it describe a new discovery, methodology, or
synthesis of knowledge?
It's mainly a synthesis of knowledge, but in part, also a new
discovery—antipsychotic drugs differ in efficacy.
Would you summarize the significance of your paper
in layman's terms?
The meta-analysis showed that some second generation antipsychotic drugs
are somewhat more efficacious than others. Although the differences were
not very big, this finding challenges a dogma that all antipsychotic drugs
are equally efficacious.
How did you become involved in this research, and
were there any problems along the way?
I got interested in evidence-based medicine more than 10 years ago and
remained fascinated by it ever since. There was an initial skepticism
towards systematic reviews and meta-analyses, but nowadays these are
accepted methods.
Where do you see your research leading in the
future?
I want to follow up on evidence-based medicine, but enter into an even more
global perspective.
Do you foresee any social or political
implications for your research?
Generally, these findings are important for decision-makers and thus,
theoretically, can have an important impact.
