The image is a line graph that displays data related to hearing levels (HL) measured in decibels (dB). The x-axis represents frequency in Hertz (Hz), ranging from 125 Hz to 8,000 Hz. The y-axis shows the HL values, which range from 0 dB to 120 dB.

There are five different lines on the graph, each representing a different condition or time point:

1. **Unaided before CI**: This line is represented by dots and appears at the top of the graph, indicating that there is no hearing aid assistance.
2. **Hearing aid aided before CI**: This line is represented by squares and is positioned slightly below the "unaided" line, suggesting a moderate level of hearing improvement with a hearing aid.
3. **CI aided 3 months after implantation**: This line is represented by triangles and shows a significant drop in HL compared to both the unaided condition and the hearing aid-aided condition before CI. It indicates that cochlear implants (CIs) provide substantial hearing improvement, especially at lower frequencies.
4. **CI aided 6 months after implantation**: This line is represented by circles and further decreases in HL values are observed compared to the previous time point, showing continued improvement with longer use of the CI.
5. **CI aided 12 months after implantation**: This line is represented by asterisks and shows a slight increase in HL at higher frequencies (around 4,000 Hz) but overall continues to show significant hearing improvement compared to both unaided conditions.

The graph clearly illustrates how the use of cochlear implants leads to improved hearing levels over time.
