Abstract:
Aim: To evaluate the persistence and adherence of subcutaneous biologics in patients with psoriatic arthritis (PsA). Patients & methods: Psoriatic arthritis patients who initiated adalimumab, certolizumab pegol, etanercept, golimumab or secukinumab between 15 January 2016 and 31 July 2017 were identified in the Truven Databases. Outcomes included discontinuation rate, persistence and adherence over 12 months. Results: Of 1558 patients included, the 12-month discontinuation rate was lowest with secukinumab (36.5%), followed by adalimumab, golimumab, etanercept and certolizumab pegol (42.6-51.6%). Mean persistence ranged from 240.7 (certolizumab pegol) to 282.8 days (secukinumab). The mean proportion of days covered was highest with secukinumab (0.67) and lowest with certolizumab pegol (0.49). Conclusion: Patients who initiated secukinumab had the lowest discontinuation rate and highest persistence and adherence over 12 months.

01:11Testing a Claim about Mean: Known Population SD
Estimating a population mean requires the samples to be distributed normally. The data should be collected from the randomly selected samples having no sampling bias. The sample size needed to be higher than 30, and most importantly, the population standard deviation should be already known.
In most realistic situations, the population standard deviation is often unknown, but in rare circumstances, when it...
01:24Testing a Claim about Population Proportion
There are two methods of testing a claim about a population proportion: (1) Using the sample proportion from the data where a binomial distribution is approximated to the normal distribution and (2) Using the binomial probabilities calculated from the data.
The first method uses normal distribution as an approximation to the binomial distribution. The requirements are as follows: sample size is large...
01:19Testing a Claim about Standard Deviation
The hypothesis testing for the claim of population standard deviation (or variance) requires the data and samples to be random and unbiased. The population distribution also must be normal. There is no specific requirement on the sample size as the estimation is based on the chi-square distribution.
As a first step, the hypothesis (null and alternative) concerning the claim about...
01:21Testing a Claim about Mean: Unknown Population SD
Estimating a population mean requires the samples to be approximately normally distributed. The data should be collected from the randomly selected samples having no sampling bias. There is no specific requirement for sample size. But if the sample size is less than 30, and we don't know the population standard deviation, a different approach is used;...
