The proportion of poorly trimmed (y-axis) fungal ITS sequences submitted to the INSDC does not decrease over time (x-axis). The regression line (dashed), which was derived by overdispersed Poisson rate regression, shows a weak but significant increasing trend (yearly relative increase of 0.047, p=0.0291).
