Abstract: Presented is a case where the death was attributed to the deliberate ingestion of an overdose of verapamil (V). Blood, urine, and gastric concentrations of the drug were determined by gas chromatography with nitrogen phosphorus detection (GC-NPD). Identification of norverapamil (NV) was made. A presumptive identification of o-demethylnorverapamil (DNV) was also made. 
Question: Does the abstract contain any numerical data?
No
