On September 24, SPHERE athletes took part in the Tours 10km-20km and marathon!

On Sunday, September 24th, the team of young researchers from SPHERE met in Tours and launched into a sports adventure by participating in the city’s annual running race. The following Monday, they discussed the best way to design slides and posters for their conference presentations, thesis defenses, and other similar events. Overall, this weekend was an enriching experience that significantly strengthened the cohesion within the team of young researchers

Restricted mean survival time to estimate an intervention effect in a cluster randomized trial

Author(s) of the publication: Floriane Le Vilain–Abraham, Elsa Tavernier, Etienne Dantan, Solène Desmée and Agnès Caille

For time-to-event outcomes, the difference in restricted mean survival time is a measure of the intervention effect, an alternative to the hazard ratio, corresponding to the expected survival duration gain due to the intervention up to a predefined time t*. We extended two existing approaches of restricted mean survival time estimation for independent data to clustered data in the framework of cluster randomized trials: one based on the direct integration of Kaplan-Meier curves and the other based on pseudo-values regression. Then, we conducted a simulation study to assess and compare the statistical performance of the proposed methods, varying the number and size of clusters, the degree of clustering, and the magnitude of the intervention effect under proportional and non-proportional hazards assumption.

SPHERE Summer Science Day in Tours

On Thursday 29 June, all SPHERE members met in Tours!

The programme included a workshop on the CARER systematic review project and a workshop on the ecological and social transition.

After a convivial lunch that was the occasion of a few photos and a meeting of young researchers, the unit exchanged on how to evaluate the future of patients after reanimation and how to involve patients and caregivers in conducting research.

SPHERE young researchers' days - March 2023

On March 27, 2023, the young researchers of SPHERE met in Nantes for their first scientific day!

On the agenda: presentation of software for the writing of the thesis manuscript and thoughts concerning the group's identity.

We started by a presentation of the LaTeX language and a feedback from former SPHERE PhD students: how did they write their manuscript? What challenges did they face ? etc.


After a convivial moment during lunch, everyone got to work:

- The first group made its first steps with Overleaf, an online Latex editor. This workshop was organized by Floriane and Yseulys.


- The second group worked on the identity of the "young researchers of SPHERE" group, which brings together a wide variety of profiles: interns, residents, PhD students, young doctors, junior engineers, postdoctoral researchers and graduate assistants. They also brainstormed on the actions we could take to stimulate scientific life, cohesion and mutual aid between young researchers.


It is already time to leave, but everyone leaves full of ideas! We will meet again in June at the SPHERE scientific day !
