 ## Data Files
 
+This repository contains two datasets:
+
+1. **ptmint_general**  
+   - Path: `data/ptmint_all_with_splits.csv`  
+   - Contents: PTMint-derived records (all PTM types included and sites both in the PPI interface and outside the interface).
+
+2. **ptmint_phospho_interfaces**  
+   - Path: `data/ptmint_interface_phospho_with_splits.csv`  
+   - Contents: a phosphorylation-focused subset restricted to records where the PTM site is mapped to a protein–protein **interface** (as defined by your preprocessing pipeline in src).
+
+
 ## Dataset Statistics
 
+### Table 1. Summary of PTM effects on protein–protein interactions
+
+| PTM types        | PTM sites | Enhance | Inhibit | Interface fraction |

+| Acetylation      | K         | 192    | 125    | 0.17 |
+| Glycosylation    | S, T      | 5      | 0      | 0.00 |
+| Methylation      | K, R      | 145    | 22     | 0.24 |
+| Phosphorylation  | S, T, Y   | 2925   | 1580   | 0.16 |
