Saturation in qualitative research: exploring its conceptualization and operationalization (2017)
Journal Article
Saunders, B., Sim, J., Kingstone, T., Baker, S., Waterfield, J., Bartlam, B., …Jinks, C. (2018). Saturation in qualitative research: exploring its conceptualization and operationalization. Quality and Quantity, 52, 1-15. https://doi.org/10.1007/s11135-017-0574-8

Saturation has attained widespread acceptance as a methodological principle in qualitative research. It is commonly taken to indicate that, on the basis of the data that have been collected or analysed hitherto, further data collection and/or analysi...

Rationale and design of BISTRO: a randomized controlled trial to determine whether bioimpedance spectroscopy-guided fluid management maintains residual kidney function in incident haemodialysis patients (2017)
Journal Article
Davie, S., Coyle, D., Dasgupta, I., Andronis, L., Farrington, K., Wilkie, M., …Caskey, F. (2017). Rationale and design of BISTRO: a randomized controlled trial to determine whether bioimpedance spectroscopy-guided fluid management maintains residual kidney function in incident haemodialysis patients. BMC Nephrology, 18, Article 138. https://doi.org/10.1186/s12882-017-0554-1

BACKGROUND: Preserved residual kidney function (RKF) and normal fluid status are associated with better patient outcomes in incident haemodialysis patients. The objective of this trial is to determine whether using bioimpedance technology in prescrib...

Identifying patients with chronic widespread pain in primary care. (2017)
Journal Article
Mansfield, K., Sim, J., Croft, P., & Jordan, K. (2017). Identifying patients with chronic widespread pain in primary care. PAIN, 158, 110-119. https://doi.org/10.1097/j.pain.0000000000000733

Chronic widespread pain (CWP) is common in the general population. It is unclear how people reporting this problem present in primary care; they may regularly consult for regional pains without being recognized as having a generalized condition. Our...

Inter-rater reliability of the Shoulder Symptom Modification Procedure in people with shoulder pain (2016)
Journal Article
Barrett, E., Hegedus, E., Sim, J., Lewis, J., & McCreesh, K. (2016). Inter-rater reliability of the Shoulder Symptom Modification Procedure in people with shoulder pain. BMJ Open Sport & Exercise Medicine, https://doi.org/10.1136/bmjsem-2016-+000181

Background Musculoskeletal conditions involving the shoulder are common and, because of the importance of the upper limb and hand in daily function, symptoms in this region are commonly associated with functional impairment in athletic and non-athlet...

Differences in subsidence rate between alternative designs of a commonly used uncemented femoral stem. (2016)
Journal Article
Al-Najjim, M., Khattak, U., Sim, J., & Chambers, I. (2016). Differences in subsidence rate between alternative designs of a commonly used uncemented femoral stem. Journal of Orthopaedics, 322 - 326. https://doi.org/10.1016/j.jor.2016.06.026

INTRODUCTION: Measurement of early subsidence of uncemented femoral stems can be used to evaluate the likelihood of long term stem component loosening and therefore clinical failure. Our aim was to evaluate the factors associated with subsidence in c... Read More about Differences in subsidence rate between alternative designs of a commonly used uncemented femoral stem..

Validation and Recalibration of Two Multivariable Prognostic Models for Survival and Independence in Acute Stroke (2016)
Journal Article
Sim, J., Teece, L., Dennis, M. S., & Roffe, C. (2016). Validation and Recalibration of Two Multivariable Prognostic Models for Survival and Independence in Acute Stroke. PloS one, 11(5), Article ARTN e0153527. https://doi.org/10.1371/journal.pone.0153527

Introduction
Various prognostic models have been developed for acute stroke, including one based on age and five binary variables (‘six simple variables’ model; SSVMod) and one based on age plus scores on the National Institutes of Health Stroke Sca...

Early Diagnosis of Pneumonia in Severe Stroke: Clinical Features and the Diagnostic Role of C-Reactive Protein (2016)
Journal Article
Warusevitane, A., Karunatilake, D., Sim, J., Smith, C., & Roffe, C. (2016). Early Diagnosis of Pneumonia in Severe Stroke: Clinical Features and the Diagnostic Role of C-Reactive Protein. PloS one, 0150269-?. https://doi.org/10.1371/journal.pone.0150269

Background
Accurate diagnosis of pneumonia complicating severe stroke is challenging due to difficulties in physical examination, altered immune responses and delayed manifestations of radiological changes. The aims of this study were to describe ea... Read More about Early Diagnosis of Pneumonia in Severe Stroke: Clinical Features and the Diagnostic Role of C-Reactive Protein.

An empirical evaluation of the impact of missing data on treatment effect (2015)
Presentation / Conference
Royes, J., Sim, J., Ogollah, R., & Lewis, M. (2015, November). An empirical evaluation of the impact of missing data on treatment effect. Poster presented at 3rd International Clinical Trials Methodology Conference, Glasgow, UK

Objectives
Missing data represent a potential source of bias in randomized clinical trials (RCTs). A simple approach that makes use of the responses subsequently obtained via reminder is proposed to assess the validity of the inferences from a missi...
