Spearman’s rank correlation coefficient, ρ, and P calculated to find out the correlation of P-gp and MRP-1 with duration of epilepsy, duration of drug-resistance and seizure frequency of MTLE patients

Drug-efflux Transporter		Duration of Epilepsy	Duration of Drug-resistance	Frequency of Seizures
MDR-1	ρ	0.03	−0.30	−0.27
	p	0.90	0.27	0.31
MRP-1	ρ	0.02	−0.03	−0.39
	p	0.92	0.90	0.14

MDR-1: Multidrug-resistance 1; MRP-1: Multidrug-resistance-associated protein-1.
