Abstract
Background: Statistical models are used to investigate the relationship between variables in statistical studies. Considering the variety of statistical models, finding the most suitable model is a complex work. This study aimed to compare different models in the treatment of infants' colic and
the misspecification of specificity.
Methods: This randomized clinical trial was conducted on 100 infants with colic in the pediatric clinic of Amir Kabir Hospital in Arak, the intervention and control groups were randomly divided into two groups. The collection and analysis of the data was performed in 2016. After teaching massage to mothers of the intervention group, they were asked to perform massage on infants three times a day during the week. In the control group, mothers can relieve the symptoms of colic by shaking the infant. Parents recorded the number and severity of crying daily in the checklist. Finally, by using different models, R software, SAS, and goodness of fit, the best model was introduced.

Results: In the massage group, the mean crying intensity of infants with colic decreased from 5.01 units on the first day to 2.47 units on the seventh day. On the other hand, the difference in mean sleep time changed from 1.81 hours in favor of the shaking group on the first day to 1.26 hours in favor of the massage group on the seventh day. Also, the severity of crying in the infants of the massage group was significantly higher than the impulse group. Regarding the grace of marginal models, the first-order self-return correlation structure was the best grace and for some variables, the model had random effects with a gamma distribution for the random component.
Conclusion: Massage can reduce infants' colic. Statistically, in the case of a nonlinear model, the variance of estimates is more than estimated to be influenced by the misspecification of the correlation structure.

Abstract
Background: Kidney stones are the third most common urinary tract disorder after prostate disease and infection. Painful attacks are the most common clinical manifestation, which is known as renal colic. The aim of the present study is to determine the effect of pethidine, pethidine and ketorolac, and ketorolac in patients with primary renal colic.
Methods: Renal colic patients at Imam Khomeini Hospital in Ilam from April 2023 and March 2023. were divided into three groups of 36 people. The first group received pethidine 25 mg, the second group received ketorolac 30 mg, and the third group received a combination of 2 drugs. A questionnaire included demographic information of the patients, heart rate, systolic and diastolic blood pressure, respiratory rate, oxygen saturation, side effects, pain intensity, length of hospitalization, and type of treatment received.
Results: After receiving the drug, the average heart rate increased in all three groups. But in group A, this increase was less than two groups, B and C, and this difference was not statistically significant (P=0.34). The average systolic blood pressure before receiving the drug was significantly higher in the three studied groups (P=0.006), which decreased after receiving the drug, but this decrease in systolic blood pressure in the three groups was not statistically significant (P=0.98). The average pain intensity before receiving the drug was 8.56 ± 1.2 in group A, 9.17 ± 0.878 in group B, and 8.86 ± 0.961 in group C. There was no significant difference between the three groups in terms of initial pain intensity (P=0.45). While the average pain intensity after receiving the medicine was significantly reduced and there was a significant difference (P<0.000).
Conclusion: Overall, the obtained results showed that ketorolac and pethidine have a faster effect and power compared to pethidine and ketorolac alone in controlling the pain of patients with renal colic, and the need for life-saving treatment is also less in this drug, and according to numerous studies, its side effects are also less.
