Disclosure control issues in complex medical data (2023)
Presentation / Conference
Green, E., Ritchie, F., Smith, J., Western, D., & White, P. (2023, September). Disclosure control issues in complex medical data. Paper presented at UNECE/Eurostat Expert Group on Statisticial Data Confidentiality, Wiesbaden

The covid19 pandemic assisted the acceleration of routine access to medical records for research. In the UK platforms including OpenSafely and NHSDigital, alongside emerging hospital trust based Trusted Research Environments (TREs), demonstrate the u...

Towards a comprehensive theory and practice of output SDC (2023)
Presentation / Conference
Derrick, B., Green, E., Ritchie, F., & White, P. (2023, September). Towards a comprehensive theory and practice of output SDC. Paper presented at UNECE/Eurostat Expert Group on Statisticial Data Confidentiality, Wiesbaden

In 2000, the statistical disclosure control of outputs (OSDC) was largely limited to models of table protection developed by and intended for national statistical institutes (NSIs), as a particular branch of general SDC theory. However, in this centu... Read More about Towards a comprehensive theory and practice of output SDC.

Disclosure risks in odds ratios and logistic regression (2022)
Presentation / Conference
Derrick, B., Green, E., Ritchie, F., & White, P. (2022, April). Disclosure risks in odds ratios and logistic regression. Paper presented at Scottish Economic Society Annual Conference 2022: Special session 'Protecting confidentiality in social science research outputs', Glasgow

When publishing statistics from confidential data, there exists a risk that the statistic might inadvertently reveal confidential information. Statistical disclosure control (SDC) aims to reduce that risk to an acceptable level. Most SDC theory is co... Read More about Disclosure risks in odds ratios and logistic regression.

Safety in numbers: Minimum thresholding, Maximum bounds and Little White Lies : The case of the mean and standard deviation (2022)
Presentation / Conference
Derrick, B., Green, E., Kember, K., Ritchie, F., & White, P. (2022, April). Safety in numbers: Minimum thresholding, Maximum bounds and Little White Lies : The case of the mean and standard deviation. Paper presented at Scottish Economic Society, Glasgow

Reporting the sample mean, sample standard deviation and sample size could in some cases lead to the unique identification of the underpinning sample. The likelihood of this reveal via direct enumeration of the possible search space decreases with i...

Investigating Browne's method (2021)
Presentation / Conference
Obodo, S., Toher, D., & White, P. (2021, September). Investigating Browne's method. Poster presented at Statistics at Bristol: Future Reserach and You 2021, Bristol

Results supports Browne’s procedure of pilot sample size determination. However the data reveals that the procedure underestimates and overestimates sample size. Fig. 1 shows 𝛼 and 𝛽 have no practical effect on degree of excess which increases as... Read More about Investigating Browne's method.

Comparison of Sentinel-2 and Landsat-8 in assessing vegetation response to soil moisture variation in droughty environments (2018)
Presentation / Conference
West, H., Quinn, N., Horswell, M., & White, P. (2018, September). Comparison of Sentinel-2 and Landsat-8 in assessing vegetation response to soil moisture variation in droughty environments. Poster presented at India-UK Water Centre - Advancing Drought Monitoring, Prediction and Management Capabilities Workshop, Lancaster, UK

The aim of this study was to determine the extent to which Sentinel-2 Normalised Difference Vegetation Index (NDVI) reflects soil moisture conditions, and whether this product offers an improvement over Landsat-8. Based on drought exposure, cloud-fre... Read More about Comparison of Sentinel-2 and Landsat-8 in assessing vegetation response to soil moisture variation in droughty environments.

A comparison of analytical methods for the two group pre- post design (2017)
Presentation / Conference
Allis, V., & White, P. (2017, April). A comparison of analytical methods for the two group pre- post design. Poster presented at UWE Student Conference, Bristol, England

Simulation demonstrates that for a two group randomized design ANCOVA is more powerful than the gain score approach For ANCOVA with an interaction term the model with pre scores X as a covariate is more powerful than the model with X + Y as the co...

Defining recovery from Complex Regional Pain Syndrome (2016)
Presentation / Conference
Llewellyn, A., Hibberd, Y., White, P., Marinus, J., Perez, R., & Brunner, F. (2016, September). Defining recovery from Complex Regional Pain Syndrome. Poster presented at International Association for the Study of Pain World Congress, Yokohama, Japan

AIM OF INVESTIGATION The longevity and complexity of symptoms in persistent Complex Regional Pain Syndrome (CRPS) leads to problems in defining recovery and evaluating the efficacy of therapeutic interventions. Using a 2-Round Delphi-based process,... Read More about Defining recovery from Complex Regional Pain Syndrome.

Understanding the physical and mental functioning of those with persistent and resolved Complex Regional Pain Syndrome to help inform treatment approaches (2016)
Presentation / Conference
McCabe, C., Llewellyn, A., Hibberd, Y., White, P., Davies, L., Marinus, J., …Moskovitz, P. A. (2016, May). Understanding the physical and mental functioning of those with persistent and resolved Complex Regional Pain Syndrome to help inform treatment approaches. Poster presented at British Pain Society Annual Scientific Meeting, Harrogate, UK

Background Pain is bio-psychosocial in nature. Recognising the inter-relationship of physical and psychological factors in Complex Regional Pain Syndrome (CRPS) has clinical implications for treating this often poorly understood chronic pain condit...
