Read the result in context
Overall mean: 86.28 for the SineMedia sample, with a 95% confidence interval of 84.82–87.74. The comparison system scored 85.25, with an interval of 83.71–86.78.
The intervals overlap; this is not evidence of statistically significant superiority. Results apply to the tested renderer and evaluation conditions, not to every company product.
