Metric Options: Counts1 Year3 YearSelecting 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
Measurement of interrupter airway resistance (R) is a convenient alternative to standard spirometry for assessing respiratory function in uncooperative young children. The aim of the present prospective study was to establish the normative data and predictive equation of Rint in Japanese preschool children. A total of 214 children were enrolled from a single kindergarten; however, 129 were excluded because they met at least 1 of the exclusion criteria, such as wheezing history or recent common cold. Expiratory Rint values were assessed in 85 of the children, but technically unsatisfactory measurements were obtained in 5 of them. Thus, 80 healthy Japanese children (39 boys and 41 girls) without any history or symptoms of respiratory tract diseases were evaluated. Their age, body height, and body weight ranges (median) were 1.67 to 6.42 (4.38) years, 79.8 to 120.9 (102.5) cm, and 10.4 to 24.9 (15.8) kg, respectively. The mean Rint was 0.93±0.25 kPa/L/s (range=0.46-1.49 kPa/L/s). The R tended to decrease with increasing age and body height (r=−0.65; P<0.01), but sex played no significant role (P=0.71). The predictive equation based on body height derived by linear regression was expiratory R (kPa/L/s)=2.513− 0.01567×body height (cm) (multiple correlation coefficient=0.653). Because 79 of the 80 measured Rint values were within 140% of the predictive Rint value, we calculated a 140% cut-off for predicting bronchoconstriction. Our results provide a reference value for evaluating the degree of airway obstruction in young Japanese children.
