I've barely touched the complex nature of the apparitions. The third commission not only had medical and scientific experts but experts from other fields.
The first commission of experts was lead by henri joyeaux who was a medical professor and i believe regarded at that time as one if not the leading medical expert in the world. He was also a communist and atheist and when to yugoslavia with the intent of debunking the apparitions. Since these experts have to publish their results , if they errored , other scientists and experts will caught their mistakes. Henri published their data in a french scientific journal and wrote a book about their investigations. If they are errors in their data i do not know about them.
