“…Continuous data are represented by mean ± standard deviation, binary data are represented by n and percentages are statistically analysed. The comparison of variables between the two groups is tested using one‐way ANOVA, 17 , 18 and a p ‐value <0.05 indicates statistical significance. The significance of ANOVA is used as the p‐value for data that satisfies normal distribution and homogeneity of variance tests.…”

To analyse the risk factors and healing factors of pharyngocutaneous fistula (PCF) in patients with laryngeal cancer after total laryngectomy, and to explore the relevant epidemiology. A retrospective analysis was conducted on laryngeal cancer patients who underwent total laryngectomy in our hospital from January 2010 to December 2022. The 349 patients included in the study were divided into a PCF group of 79 and a non‐PCF group of 270. Perform one‐way analysis of variance and multivariate logistic analysis on various data of patients included in the statistics, and analyse the risk factors and healing factors of PCF. Smoking, history of radiation therapy for laryngeal cancer, history of chemotherapy for laryngeal cancer, tumour location (larynx, pharynx, oesophagus), preoperative albumin, postoperative proteinaemia, <99 haemoglobin, postoperative haemoglobin, postoperative C‐reactive protein (CRP) level are the risk factors for PCF. Also, radiation therapy and postoperative proteinaemia were the main reasons for preventing PCF healing. Smoking history, laryngeal cancer, radiation therapy, albumin, haemoglobin and CRP are risk factors for postoperative PCF after total laryngectomy, while radiation therapy and postoperative hypoalbuminaemia are key factors affecting PCF healing.

“…For this purpose, the F-score in one-way ANOVA can be used. One-way ANOVA is a suitable method for investigating the effect of each independent variable (input indicators) on the dependent variable (flight delay) 26 . In the proposed method, this analysis is performed on each input indicator to determine the significance level of its effect on flight delay in the form of an F-score.…”

The prediction of flight delays is one of the important and challenging issues in the field of scheduling and planning flights by airports and airlines. Therefore, in recent years, we have witnessed various methods to solve this problem using machine learning techniques. In this article, a new method is proposed to address these issues. In the proposed method, a group of potential indicators related to flight delay is introduced, and a combination of ANOVA and the Forward Sequential Feature Selection (FSFS) algorithm is used to determine the most influential indicators on flight delays. To overcome the challenges related to large flight data volumes, a clustering strategy based on the DBSCAN algorithm is employed. In this approach, samples are clustered into similar groups, and a separate learning model is used to predict flight delays for each group. This strategy allows the problem to be decomposed into smaller sub-problems, leading to improved prediction system performance in terms of accuracy (by 2.49%) and processing speed (by 39.17%). The learning model used in each cluster is a novel structure based on a random forest, where each tree component is optimized and weighted using the Coyote Optimization Algorithm (COA). Optimizing the structure of each tree component and assigning weighted values to them results in a minimum 5.3% increase in accuracy compared to the conventional random forest model. The performance of the proposed method in predicting flight delays is tested and compared with previous research. The findings demonstrate that the proposed approach achieves an average accuracy of 97.2% which indicates a 4.7% improvement compared to previous efforts.

This study aims to investigate the Turkish validity and reliability of the International Fitness Scale (IFIS) and the Self-Perceived Health-Related Physical Fitness Questionnaire for Children (SPHQ-C) aged 10–17. The measurement tools were translated into Turkish by two independent researchers and back-translated. Then, the content validity was established with a group of 13 individuals (Sample 1) who presented to the sports medicine clinic. The pilot application phase was initiated. A sample of 372 individuals (Sample 2) studying in the provincial center was selected for piloting the measurement tools with the ALPHA-FIT Test Battery. The test–retest application of the measurement tools with a 15-day interval was carried out with 207 individuals (Sample 3) not included in Sample 2. The authors calculated that the content validity ratio values for the items in the IFIS ranged from 0.85 to 1.00, with a content validity index of 0.94 for the scale. In the SPHQ-C, these values were found to be between 0.92 and 1.00, with a content validity index of 0.99. According to the Z-score difference analysis for both measurement tools, the construct validity of all items was achieved (p < 0.05). In the Bland–Altman plot test conducted for the IFIS-TR, the mean difference was calculated as 0.11, the standard deviation of the differences was 1.57, and the p-value was determined as 0.31. For the SPHQ-C-TR, the mean difference was −0.15, the standard deviation of the differences was 1.95, and the p-value was determined as 0.26. The Kappa coefficients for the items of the IFIS-TR ranged from 0.45 to 0.52, while for the SPHQ-C-TR, the Kappa coefficients ranged from 0.47 to 0.75. Confirmatory factor analysis conducted on Sample 2 confirmed model fit indices with covariance among some items of the measurement tools (IFIS-TR: e1–e3; SPHQ-C-TR: e1–e2, e1–e3, e2–e3, e3–e4, e6–e7, e8–e9). The IFIS and SPHQ-C measurement tools have been adapted into Turkish, and their validity and reliability have been established.
