In conclusion, the frequentist method expresses how consistent the data is with H0 in terms of p-values, with no consideration of the probability of H1.

The JASP software enables the performance of both frequentist and Bayesian analyses in a friendly and intuitive way, and its application is displayed at the end of the paper. The Bayesian prediction is not dichotomous but is expressed in continuous scales of the Bf and of the posterior odds. Prior odds are the researcher's belief about the probability of H1, and the Bf quantifies how consistent the data is concerning H1 and H0. The Bayesian method calculates the probability of H1 and H0 considering prior odds and the Bayes factor (Bf).
The H0 is rejected or not based on a p threshold of 0.05, and this dichotomous approach does not express the probability that the alternative hypothesis (H1) is true. The frequentist p-value is the probability of finding a value equal to or higher than that observed in a study, assuming that the null hypothesis (H0) is true. The present is a gentle narrative review of the frequentist and Bayesian methods intended for physicians not familiar with mathematics. A poor understanding of both statistical frameworks is common among clinicians. Given the limitations of frequentist method for null hypothesis significance testing, different authors recommend alternatives such as Bayesian inference. Nonligation of the dorsal vascular complex and preservation of the puboprostatic ligaments and the endopelvic fascia improved urinary continence compared with the traditional nonpreservation technique, with no impact in terms of bleeding and oncologic outcomes. There were no significant differences between the groups regarding potency and oncologic outcomes. The continence rate (0 pads/day) for the preservation technique group versus the traditional technique group at 1, 3, 6, and 12 months was, respectively, 53.3% versus 30% (P =. The probability of continence recovery was significantly higher in the preservation technique group than in the traditional technique group (hazard ratio = 0.50, 95% CI = 0.31-0.81). There were no significant differences in intraoperative bleeding, discharge hemoglobin level, blood transfusion rate, length of hospitalization, and drop in the hemoglobin level. Operative time was significantly lower in the preservation technique group (229.6 vs. The mean patient age was 59 years in both groups.
A single surgeon performed all procedures.ĭemographic and preoperative characteristics were similar. Information from 30 patients who underwent the preservation technique was prospectively collected and compared with data from 60 patients who underwent the nonpreservation traditional technique. The UIS has The Technological Park of Guatiguará (PTG) which is today the most advanced urban, technological and business project within the policy of technological parks established by the national government There are 14 research centers and specialized laboratories working with the national productive sector and the first two technology-based companies.To evaluate the impact on continence rate during 1-year follow-up of a preservation technique that included nonligation of the dorsal vascular complex and sparing of the puboprostatic ligaments and the endopelvic fascia during laparoscopic radical prostatectomy. According to the QS ranking, the UIS is the 3rd best Public University in Colombia and 73rd in Latin America. In the Latin America Ranking of 2018 UIS was classified in the 51-60th group and in the World University Ranking of 2019 was in the 801-1000th best universities. Is one of the best universities in the country, recognized by Times Higher Education (THE) as the third best in Colombia. programs, among its five faculties.UIS is divided into four campuses in Bucaramanga and four additional campuses in mid-sized cities of the region (Barrancabermeja, Barbosa, Socorro, and Malaga). UIS offers a total of 44 Bachelor and 113 postgraduate degrees, including 50 Masters and 10 Ph.D. It has around 22,000 undergraduate and graduate students at the highest level in most of the areas of knowledge (Physic-chemical and Physic-mechanical engineering, Basic Sciences, Human Sciences, Health, and Life Sciences). The Universidad Industrial de Santander (UIS) was Founded in 1948, in Bucaramanga, Santander.
