✦ Synopsis

A test statistic for detecting the presence of a non-linear trend in a sequence of independent observations is proposed. The test is useful for determining when the use of the non-parametric slope estimator as a summary of the trend is appropriate. The asymptotic normality of the test is established and simulation results indicate its accuracy for practical applications. An example is used to illustrate the test.

## Abstract Approximately 5% of patients with cervical dystonia receiving repeated botulinum neurotoxin A (BoNT/A) injections develop secondary loss of treatment benefit. Currently available tests to directly detect neutralizing BoNT/A antibodies (BoNT/A‐AB) are either expensive or time consuming.
