The Mean ± 2SD method effectively serves to identify the cut-off points that would be expected to yield 95% specificity and 95% sensitivity respectively. For a scale which is designed such that higher scores are more indicative of a positive diagnosis these points are calculated as follows: looking first within the non-clinical sample, the Mean Score + 2 Standard Deviations (SD) represents 95% specificity; similarly, within the clinical sample, the Mean Score – 2 SD represents 95% sensitivity. These points can be considered to provide the limits for the choice of a cut-off point. Assuming, as will normally be the case, that the Mean + 2SD for the non-clinical sample is greater than the Mean – 2SD for the clinical sample, then the point of intersection of the two normal curves offers a natural point of compromise [ 3]. Our analysis includes a capture-recapture method to estimate the prevalence of FOP cases in France as of January 1st 2012. The prevalence was calculated for this date by dividing the number of living FOP patients by the resident population. The confidence interval was calculated using Wilson’s method with a continuity correction of a Poisson law [ 15]. On the prevalence day, the population was 65,400,000 in Metropolitan (mainland) France and overseas Departments ( https://www.insee.fr/fr/statistiques/1372599?sommaire=1372680).

Before CEMARA data were linked to PMSI, patients in the CEMARA database were informed by mail of the nature of the data transmitted, the reason for processing data, of the people and entities who received the data, and their rights of access, opposition and rectification of data recorded during the study.

Competing interests Full size image DHA/AA promoted GPR120 interaction with NLRP3 and decreased NLRP3 inflammasome assembly in LPS-induced Kupffer cells In addition to these methodological differences, the environment has changed in recent years to favor increased identification of FOP affected individuals. The internet provides access to information about FOP, and search engines allow individuals with questions about signs and symptoms to identify specific diseases that match their condition, including FOP. Also, advances in research have led to increased physician awareness of FOP and more efficient diagnostic capabilities (molecular testing), both of which assist in the identification of FOP-affected individuals, particularly in atypical forms. Finally, informatics systems such as CEMARA make it easier to conduct population studies with specific disease groups such as FOP. Relevance and extrapolation to other countries

The 2 databases used in this study, CEMARA and PMSI, capture patient data in different ways that result in different coverage and quality. CEMARA captures diagnostic data from expert national centres (Centre of Reference “Maladies Osseuses Constitutionnelles”- CR-MOC) where FOP patients’ diagnosis is validated by physicians with expertise in the disease, through their out-patient or in-patient clinics. The PMSI system captures ICD diagnostic codes for in-patient clinics only. Fresh livers were fixed with 4% paraformaldehyde and paraffin-embedded, and the sections were stained using H&E.
