Attention, Executive Function, Behavior, and Electrocortical Function, Significantly Improved With 19-Channel Z-Score Neurofeedback in a Clinical Setting: A Pilot Study.
A small pilot reported improvements in attention, behavior and other measures after training. Its design cannot establish whether neurofeedback caused the changes.

Clinician summary
One-tailed tests favored post-treatment scores across outcome-specific groups. These group counts should not be added together as independent participants.
How to interpret the findings
Uncontrolled pre/post design, small outcome samples and possible practice or expectancy effects. The study does not establish superiority over fewer-channel protocols.
