NIH recognized the need to understand the potential impact of cancer on their patient’s health, particularly concerning blood pressure. NIH hired our team of statistical consultants to conduct a comprehensive investigation to determine if there were significant differences in blood pressure levels between patients diagnosed with cancer and those without cancer. The purpose of this study was to contribute to the broader understanding of health-related factors associated with cancer diagnoses.
We determined the sample size using a robust power analysis to ensure precision. We specified the anticipated effect size, significance level (alpha), and desired power (1—beta) parameters.
The foundation of this research project was a substantial dataset comprising survey responses from 10,000 patients collected over four years. This dataset provided a comprehensive platform for examining the potential differences in blood pressure levels among patients with and without cancer.
The assumption of normal distribution was not met. Therefore, we conducted nonparametric methods to address the research question and evaluate the hypothesis using the statistical software SAS.
The central hypothesis guiding the research efforts was H1—There are significant differences in blood pressure levels between patients with and without cancer. The research rigorously tested this hypothesis, seeking to determine whether cancer diagnoses had a statistically significant effect on patients’ blood pressure levels.
The analysis yielded compelling findings that provided valuable insights into Johns Hopkins Medicine’s inquiry. The research results indicated a statistically significant difference in blood pressure levels between patients diagnosed with cancer and those without cancer. This discovery highlighted the effect of cancer diagnoses on blood pressure levels among patients.
NIH derived valuable insights from this research endeavor. By learning that there were significant differences in blood pressure levels between patients with and without cancer, NIH gained a deeper understanding of the potential health implications associated with cancer diagnoses. This knowledge informed Johns Hopkins Medicine’s healthcare strategies, patient care plans, and further research into cancer-related health outcomes
