Hypothesis testing is integral to health research and is commonly completed through frequentist statistics focused on computing p values. p Values have been long criticized for offering limited information about the relationship of variables and strength of evidence concerning the plausibility, presence and certainty of associations among variables. Bayesian statistics is a potential alternative for inference-making. Despite emerging discussion on Bayesian statistics across various disciplines, the uptake of Bayesian statistics in health research is still limited. ⋯ Health researchers should supplement frequentists statistics with Bayesian statistics when analysing research data. The overreliance on p values for clinical decisions making should be avoided. Bayes factors offer a more intuitive measure of assessing the strength of evidence for null and alternative hypothesis.

Despite the widespread recommendation to engage in therapeutic exercise for the treatment of low back pain (LBP), there is conflicting evidence regarding clinical outcomes and effectiveness. Poor methodological quality may be to blame for reducing the overall strength of evidence for this intervention, yet little is known about the difficulties researchers encounter when designing and implementing their study methods. ⋯ Statistical power, study length and/or follow-up, and inclusion criteria were the three most commonly reported categories of SALs in exercise trials for LBP. Lack of long-term follow-up, inadequate sample size and inclusion of specific populations were the most common subcategories. Research protocols recognizing and avoiding these limitations will enhance the overall quality of evidence of exercise therapy trials for LBP.

This study explored what patients identified with cervical cancer know about the link between human papillomavirus (HPV) and cervical cancer and where they learned this information. Patients share a great deal of information with family, friends and colleagues and we were interested in the accuracy and sources of information they are sharing. ⋯ Patients may serve as a conduit for information about their condition and may be informal 'educators' in the community. It is important to make certain that these opportunities are informed by information obtained from trusted and accurate sources.

Review Comparative Study
(Cost-)effectiveness of personalised multimodal physiotherapy compared to surgery in patients with cervical radiculopathy: A systematic review.
Cervical radiculopathy is initially typically managed conservatively. Surgery is indicated when conservative management fails or with severe/progressive neurological signs. Personalised multimodal physiotherapy could be a promising conservative strategy. However, aggregated evidence on the (cost-)effectiveness of personalised multimodal physiotherapy compared to surgery with/without post-operative physiotherapy is lacking. ⋯ Considering the clinical importance of accurate management recommendations and the current low level of certainty, high-quality cost-effectiveness studies are needed.
