Categorical Variable Distribution Study Results IV: PRESERVE

- For the most common result value of NEGATIVE, Stanford and Umiami, which were identified as anomalous in the cross-sectional output, also appear anomalous here. - Hopkins was not identified as anomalous in the cross-sectional output, but the longitudinal trend is lower than the rest of the network with the exception of a brief period around 2016/2017. - The "OT" result category has relatively consistent longitudinal trends across the time period, though the values are heterogenous between institutions.
