"This case report gives hope that the KD might improve clinical outcomes for some patients with NSCLC. The tumor shrinkage, survival time, spectacular improvement in physical condition, and the restoration of daily attitudes are encouraging for further application of this therapeutic approach to larger numbers of patients."

Under "Case presentation" they call out that the patient is right handed... "A 54-year-old right-handed man presented with headache,"... is that a common thing to pay attention to in the type of research? I can see why they note he's a smoker, but seeing right-handed surprised me.
