Journal ArticleDOI
Comorbidity prevalence among cancer patients: a population-based cohort study of four cancers
Helen Fowler,Aurélien Belot,Libby Ellis,Camille Maringe,Miguel Angel Luque-Fernandez,Miguel Angel Luque-Fernandez,Edmund Njeru Njagi,Neal Navani,Neal Navani,Diana Sarfati,Bernard Rachet +10 more
TL;DR: In all four cohorts, the odds of having a comorbidity and the probability of multipleComorbidities were consistently highest in the most deprived cancer patients, and the association between cancer comor bidity and socio-economic position was described.
Journal ArticleDOI
Association between age, deprivation and specific comorbid conditions and the receipt of major surgery in patients with non-small cell lung cancer in England: A population-based study
Aurélien Belot,Helen Fowler,Edmund Njeru Njagi,Miguel Angel Luque-Fernandez,Camille Maringe,Winnie Magadi,Aimilia Exarchakou,Manuela Quaresma,Adrian Turculet,Michael D Peake,Neal Navani,Bernard Rachet +11 more
TL;DR: Comorbidities play an important role in whether patients undergo surgery, but do not completely explain the socioeconomic difference observed in early stage patients; future work investigating access to and distance from specialist hospitals, as well as patient perceptions and patient choice in receiving surgery, could help disentangle these persistent socioeconomic inequalities.
Journal ArticleDOI
A joint survival-longitudinal modelling approach for the dynamic prediction of rehospitalization in telemonitored chronic heart failure patients
TL;DR: A dynamic prediction approach, based on calculating dynamically-updated patient-specific conditional survival probabilities, and their confidence intervals, from a joint model for the time-to-rehospitalization and thetime-varying and possibly error-contaminated biomarker, which provides immense contribution to heart failure management.
Journal ArticleDOI
Persistent inequalities in 90-day colon cancer mortality: an English cohort study.
Helen Fowler,Aurélien Belot,Edmund Njeru Njagi,Miguel Angel Luque-Fernandez,Camille Maringe,Manuela Quaresma,M Kajiwara,Bernard Rachet +7 more
TL;DR: Ninety-day probability of death rose with increasing deprivation, even after accounting for the main prognostic factors, and the differences between deprivation-specific averaged predicted probabilities of death were greatly reduced but persisted.
Journal ArticleDOI
A flexible joint modeling framework for longitudinal and time-to-event data with overdispersion
Edmund Njeru Njagi,Geert Molenberghs,Dimitris Rizopoulos,Geert Verbeke,Michael G. Kenward,Paul Dendale,Koen Willekens +6 more
TL;DR: Using a case study in chronic heart failure, it is shown that model fit can be improved, even resulting in impact on significance tests, by switching to the extended framework, and easily estimate the framework, by maximum likelihood, in standard software.
