+The file here contains results from the [MACAW](https://github.com/Devlin-Moyer/macaw) `dead_end_test` and `duplicate_test` tests, and from cell-line specific gene essentiality prediction based on the [Hart _et al._ (2015)](https://doi.org/10.1016/j.cell.2015.11.015) dataset.
 
 The test results shown here were obtained by the GitHub Actions run in **PR #829**, and will be updated by any subsequent PR. Summary results are shown as a comment in the corresponding PR.
 
-### `dead_end_test`
+### MACAW: `dead_end_test`
 Looks for metabolites in Human-GEM that can only be produced by all reactions they participate in or only consumed, then identifies all reactions that are prevented from sustaining steady-state fluxes because of each of these dead-end metabolites. The simplest case of a dead-end metabolite is one that only participates in a single reaction. Also flags all reversible reactions that can only carry fluxes in a single direction because one of their metabolites can either only be consumed or only be produced by all other reactions it participates in.
 
-### `duplicate_test`
+### MACAW: `duplicate_test`
 Identifies sets of reactions that may be duplicates of each other because they:
 
 - Involve exactly the same metabolites with exactly the same stoichiometric coefficients (but potentially different associated genes).

+### Cell-line specific gene essentiality
+Evaluate gene essentiality predictions in 5 cell-line specific GEMs with experimental fitness data gathered from the [Hart _et al._ (2015)](https://doi.org/10.1016/j.cell.2015.11.015).
+
+Cell-line specific GEMs are constructed with tINIT2 for DLD1, GBM, HCT116, HeLa and RPE1 cell lines. Then, the `metabolicTasks_Essential.txt` list of tasks is used to identify essential genes in each of these models. The predicted gene essentiality is compared to results from a high-throughput CRISPR-Cas9 screen for identifying genes that affect fitness. Only the summary statistics of this comparison are kept.
