#### **Search**
The literature search was performed in PubMed.
Two *comprehensive search filters* were created for this project: one for to search the [animal literature](https://osf.io/qnctj/) and another to search the [human literature](https://osf.io/w9ufg/). The *selection of the search components* that are in these filters is summarized in a log file that can be found on [OSF](https://osf.io/bmkxv/).
- The [*first search*](https://osf.io/vtn7m/) was done on
18.10.2016 (animal literature, 178 hits) and 12.10.2016 (human literature, 292 hits).
- The [*second search*](https://osf.io/grptx/) was performed on 6.1.2020
(animal literature, 292 hits; human literature, 434 hits).
PMIDS were downloaded to txt file ([clinical](https://osf.io/7kdmu/) & [preclinical](https://osf.io/fs2gq/)) and compared with PMIDS of first search (derived from TRACE dataset). R-code is on [Github](https://github.com/mscsep/TRACE).
- A [*third search*](https://osf.io/e9wmt/) was performed with updated SC's, specifically for learning and memory.
#### **Screening**
An overview of the [*inclusion and exclusion criteria*](https://osf.io/s892j/) is on OSF.
Animal models were considered models for PTSD if they are described in the two papers below:
