Credibility in Science & Research

For the systematic review Beta‐blockers for suspected or diagnosed acute myocardial infarction, Cochrane reviewers had to correct for multiple endpoints. They turned to our relative risk calculator to run exact confidence interval calculations (specifically at 97.5% and 98%) to make sure their statistical conclusions were solid.

In Localized cardiac small molecule trajectories and persistent chemical sequelae in experimental Chagas disease, biochemists analyzed small molecule variations in infected cardiac tissue. To test associations across their small cohort tables where an exact test was appropriate for the sample sizes involved, they used our Fisher’s exact test calculator.

In a meta-analysis combining 292 studies and almost 98,000 pregnant women, Association of maternal lipid profile and gestational diabetes mellitus, the researchers needed to reconcile lipid measurements reported in different units: some clinics reported cholesterol in mg/dL while others used mmol/L. They used our cholesterol units converter to convert and align all lipid values across the dataset.

In the clinical review Probiotic supplementation during antibiotic treatment is unjustified in maintaining the gut microbiome diversity, the authors compared gut flora diversity across several clinical trials. They linked to our Shannon diversity index calculator to explain how species richness and evenness are quantified in ecological sampling.

Clinical and professional guidance

The official guideline panel for the European Association of Urology published the European Association of Urology Guidelines on Non–muscle-invasive Bladder Cancer (Ta, T1, and Carcinoma in Situ). In their recommendations for oncologists, they explicitly cited our EORTC bladder cancer recurrence and progression calculator, enabling clinicians to quickly calculate individual patient recurrence scores.

In the official guideline Thirty Obesity Myths, Misunderstandings, and/or Oversimplifications: An Obesity Medicine Association (OMA) Clinical Practice Statement (CPS) 2022, clinicians addressed BMI limitations. They highlighted our army body fat calculator as a useful, accessible circumference method for assessing body fat in muscular people.

Peer-reviewed specialist research

In the testing accuracy paper Investigating the Sensitivity of Nasal or Throat Swabs: Combination of Both Swabs Increases the Sensitivity of SARS-CoV-2 Rapid Antigen Tests, microbiologists compared swab diagnostic sensitivity. They ran paired calculations on our McNemar’s test calculator to obtain exact p-values for paired samples.

In the chemical engineering paper Membrane transport behavior characterization method with constant water flux in pressure-assisted forward osmosis, published in the journal Desalination, the authors studied osmotic water flux. They cited our osmotic pressure calculator to benchmark osmotic values across different concentration gradients.

Major institutional/editorial recognition

In their patient guide on cardiorespiratory fitness, VO2 max: What is it and how can you improve it?, the Harvard Health editorial team points readers directly to our VO2 max calculator. They recommend it as a practical tool for people who want to track aerobic capacity and heart health outside of an expensive lab test.

In the ecological feature Saving a Forest of One, NASA science writers wanted to explain just how massive the clonal Pando aspen forest really is. To translate millions of kilograms of biological mass into comparisons regular readers can picture, they linked to our weird units converter.

On their public health site, Mercury: From Source to Seafood, Dartmouth researchers study heavy metals in marine life. They recommend our fish mercury calculator so people can check how much methylmercury they ingest based on fish species and portion size.

In their training materials for the Biotechnician Assistant Credentialing Exam, BACE Preparation - Prepare With Confidence, the University of Florida directs biotech students to our significant figures calculator to verify experimental measurements and laboratory precision rules.
