The PEARL score is a simple tool that can effectively stratify patients’ risk of 90-day readmission or death, which could help guide readmission avoidance strategies within the clinical and research setting. It is superior to other scores that have been used in this population. So the real-life user failure rate is less than 1%. An array is a variable that stores an ordered list of scalar values. The 3rd call shows that index returns 0 when the second string is a prefix of the first string. Actual failure rates are higher than perfect-use rates for a variety of reasons: The factor 1200 is the number of months in 100 years. 148. Failure rates may be calculated by either the Pearl Index or a life table method. Obstetrics A formula that allows comparison of the efficacy of contraceptive methods, calculated as the pregnancy rate in population divided by 100 yrs of exposure. Pearl Index. The Pearl index will be determined by the number of unintentional pregnancies related to 100 women. 2) life – table analysis . Pearl Index (PI) for ideal use is 0.6 and for typical use 0.8. The first call to index returned 10, because the string "cat" starts on the 10th character. The index() function is used to determine the position of a letter or a substring in a string. A "perfect-use" rate is where any rules of the method are rigorously followed, and (if applicable) the method is used at every act of intercourse. There are no studies indicating a reduced efficacy of copper IUDs in obese women compared to normal-weight women. 2 shows the Kaplan–Meier cumulated probability of nonpregnancy as a function of the number of cycles for typical … The second call to index returned -1 indicating there is no "dog" in that sentence. If three pregnancies occur during this period in this group, the Pearl index will be 3.0. The estimated Pearl Index, calculated based on data from … E.g. In applying the above formula : The total accidental pregnancies shown in the numerator must include every known conception, whatever its outcome. PEARL INDEX • It is defined as the number of “ failures per 100 women years of exposure (HWY) .” • It is normally used for studying the effectiveness of a contraceptive. Using the Perl index() function Introduction. Using the data in Table 2, we calculated a perfect-use Pearl Index of 1.0 (95% CI: 0.5–1.5) pregnancies per 100 woman-years and a 13-cycle pregnancy probability of 1.0% (95% CI: 0.5–1.5). See Breast feeding, Coitus interruptus, Condoms, Morning-after pill, Contraception, … Fig. Perl - Arrays. To refer to a single element of an array, you will use the dollar sign ($) with the variable name followed by the index of the element in square brackets. The structural formula for lactic acid is: Lactic acid is designated chemically as 2-hydroxypropanoic acid with an empirical formula of C 3 H 6 O 3 and a molecular weight of 90.08 g/mol. • The two methods being used for measuring contraceptive efficacy are:- 1) Pearl index . Array variables are preceded by an "at" (@) sign. For example, in the word "frog" the letter "f" is in position 0, the "r" in position 1, the "o" in 2 and the "g" in 3. After prolonged continuous use the cumulative pregnancy rate is 1.6% at 7 years and 2.2% at 8 and 12 years [13,14]. 100 women can us e a particular contraceptive for 1 year each with the method to be examined.
