Indicate the presence of numerical data in the abstract (whether numerical data plays a key role in medical records), solely using the information from the abstract.

Example Input: Abstract: Twelve patients with intractable rheumatoid arthritis were treated with antilymphocyte globulin (ALG), prednisolone and a cytotoxic agent, usually azathioprine, and were followed for 1 year. There was a significant (p less than 0.05) improvement in the mean score for early-morning stiffness, grip strength and the severity of nodules and vasculitis at 6 weeks and 3 months when compared to the initial visit. However, in most patients, this benefit was not sustained despite continued cytotoxic and steroid therapy. A rise in the haemoglobin and fall in ESR was maintained throughout the study period.

Example Input: 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.

Example Input: Abstract: Two hundred ninety-seven long-term photochemotherapy (PUVA)-treated patients from an original cohort of 418 subjects reported in 1980 were reevaluated in a second follow-up in order to determine the risk of tumor development under long-term PUVA. Within an observation period of up to 8 years (mean, 63.1 months) six patients with squamous cell carcinomas and three with basal cell carcinomas were observed. Eight of the nine tumor patients had been exposed to potential carcinogens such as arsenic and/or ionizing radiation prior to PUVA treatment. Five with squamous cell carcinomas were skin type I or II; in four of the six patients with squamous cell carcinomas the tumors were located on unexposed skin areas. The mean cumulative ultraviolet A (UVA) dose in three of the six squamous cell carcinoma patients was three times as high as that in the group of nontumor patients. The other three squamous cell carcinoma patients had lower mean doses than nontumor patients, as did the three patients with basal cell carcinomas. Although the cumulative UVA dose may eventually turn out to be relevant for PUVA carcinogenesis, our present data do not sufficiently substantiate a correlation between cumulative UVA dose and squamous cell carcinoma formation in PUVA-treated patients. This report confirms that previous exposure to carcinogens appears to be the most important factor for nonmelanoma skin tumor formation in long-term PUVA patients.
