Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Under certain conditions the determination of the tryptic activity, especially of the chymotryptic activity in the feces mostly of infants in the first 4-6 weeks of life is considered to be an important step in the diagnosis of cystic fibrosis. The tryptic and chymotryptic activity in the feces of children with cystic fibrosis declines when the substitution of pancreatic enzymes is stopped. On resubstitution, the activity rises in relation to the dose and attains the activity related to age as found in healthy children. A comparison of the proteolytic activity with the fat content of the feces during the study period without the enzyme substitution and during the period when the enzyme dosage varied showed no significant correlation. It is not possible to postulate a poor excretion of fats merely from the high proteolytic activity of the feces because the fecal proteolytic activity and the fat excretion are not inversely proportional to one another. For this reason, one cannot conclude that the grade of the proteolytic activity in the feces of patients with cystic fibrosis is a yardstick for the total digestive process when they are under pancreatic enzyme substitution. © 1976 Springer-Verlag.
