Determine if the following text contains a data availability statement. Answer with 'yes' or 'no'.

Text: The current results should be considered relative to a few study limitations. The CFS **data** did not specify the nature of proactive activities that patrol, DRT officers, or investigators were engaged in. Furthermore, although the coding of the ten call categories analyzed were informed by prior research (Wu & Lum, 2017), idiosyncrasies associated with the study departments' method of cataloging and recording call information did not always allow for direct comparisons to prior research on COVID-19's impact on police services. Similarly, measuring proactivity solely through self-initiated activities from CFS **data** is not a flawless indicator. Officers may engage in proactive work that is not captured in these **data** (Lum, Koper, et al., 2020). However, this method has been established as a reasonable way to distinguish proactivity from reactivity (Lum, Koper, et al., 2020;Wu & Lum, 2017;Zhang and Zhao, 2021).<|eot_id|><|start_header_id|>assistant<|end_header_id|>
