 \subsection{Data Source and Characteristics}\label{subsec:data_background}
 This study is based on a dataset collected from users of the \emph{OvulaRing}~\cite{noauthor_ovularing_nodate},
 an intravaginal wearable sensor developed by VivoSensMedical GmbH, located in Leipzig, Germany~\cite{noauthor_vivosens_nodate}.
+VivoSensMedical is supported by the European Regional Development Fund (EFRE), Saxon State Ministry for Economic Affairs,
+Labour and Transport (SMWA) and the State Ministry of Science and Fine Arts (SMWK) and the City of Leipzig.
+OvulaRing has been financed by the startup grant `EXIST Gründerstipendium` from the Federal Ministry of Economics and Technology.
 The device continuously records intravaginal core body temperature at 5-minute intervals.
 The sensor itself measures approximately 1\,cm $\times$ 1\,cm $\times$ 2\,cm and is embedded in a silicone ring with a diameter of 5\,cm for ease of use.
 It pairs with a smartphone via Bluetooth to synchronize and upload recorded data to a secure database.
