Contributors: SFo, SFr, AW, and you may JC met with the suggestion on analysis

AW and JC developed and you can organized the research. AW drawn up the fresh manuscript. BC performed data administration. BC and you may PN did statistical analyses. AW and JC ensured endeavor and read government. Most of the people (AW, PN, ML, BC, TP, LD, ALB, IY, SFo, SFr, and JC) contributed to translation of study and revised the manuscript. Most of the experts accepted the final manuscript. The latest associated copywriter (AW) attests that most noted authors see authorship conditions which no anybody else conference this new conditions have been excluded. AW and you can JC is the guarantors.

Funding: This research was financed by French National Health insurance Fund (CNAM) therefore the Wellness Equipment Epidemiology Scientific Interest Class (ANSM-CNAM EPI-PHARE SIG). AW, JC, and BC is professionals from French National Medical insurance Financing, PN is a member of staff of the French National Department getting Medicines and you will Fitness Activities Safety. The current report is short for the brand new feedback of your authors and you can really does never mirror the positioning of its companies.

Competing welfare: All people have finished this new ICMJE consistent disclosure form in the and declare: help regarding French Federal Medical insurance Funds (CNAM) additionally the Fitness Tool Epidemiology Medical Notice Class (ANSM-CNAM EPI-PHARE SIG) for the recorded work; zero monetary matchmaking which have any companies that may have an interest in the submitted are employed in the earlier three-years; not one relationship otherwise activities which will seem to have swayed the fresh new submitted work.

The lead journalist (AW) affirms that this manuscript was a respectable, accurate and you will clear account of your own investigation being advertised; one no key factors of study was indeed omitted; and this any discrepancies throughout the data while the planned (and you can, if relevant, registered) was basically informed me.

Dissemination to members and relevant diligent and you may public groups: The outcome was basically made available to patient relationship representatives. Clients who had put cyproterone acetate milligrams across the early in the day a few age (as well as their general practitioners) gotten a development page in the home getting detailed information on which to do (supplementary procedure S18).

Research populations

A couple other awareness analyses was indeed conducted: study of your own 2007-14 unwrapped or handle classification chief cohort have been paired to have age at initiation and you can time of go after-right up, and you will an effective nested case-control learn from the brand new 2007-fourteen main cohort.


Chance, relative exposure, and you can adjusted possibility proportion out of meningioma according to connection with cyproterone acetate (main cohort, 2007-14; n=253 777)

Brand new estimated number of people that have meningioma due to cyproterone acetate was more than 500 for the France on period 2007-15 (62 a year; second thing S16). That it imagine lies in a conservative computation that doesn’t take into account people with a diagnosis more than one season just after discontinuation from cyproterone acetate, individuals with a diagnosis after an initial group of very quite launched (control group) and you can next resumption of cyproterone acetate, and you will meningiomas handled because of the medical go after-up in the place of businesses or radiotherapy.

Likewise, the current presence of progesterone receptors into the arachnoid tissue, where meningiomas happen, could have been noted for five ages.5556575859 Several authors keeps said a great heterogeneous shipment away from progesterone receptors with respect to the website from meningiomas. A beneficial rostrocaudal gradient out of progesterone receptors, that have increased density away from receptors about head legs, have often already been said, and you can are confirmed by a number of books.6061 All of our looking for away from a predominance out-of prior skull feet meningiomas connected with access to cyproterone acetate, an excellent progestogen, is in keeping with these types of physical conclusions.

Advantages from the analysis

Numerous restrictions also concern the latest systematic and you may happn active today histological services from meningioma. SNDS cannot include analysis towards the result of magnetic resonance imaging otherwise histology, otherwise if or not meningiomas is actually single otherwise numerous, with the exception of procedures that cover collection of anatomical places.
