Randomized Controlled Trial
High individual pain variability in people living with HIV: a graphical analysis.
People living with HIV (PLWH) frequently experience pain. Following calls to analyse individual-level data in addition to group-level data in pain studies, we compared individual and group-level changes in pain prevalence, intensity and number of pain sites over 48 weeks in a large cohort of PLWH. This is the largest ever cohort study of pain in PLWH, and is the first to report pain at the level of the individual. ⋯ This graphical analysis highlights the high variability in pain (pain prevalence, intensity and body sites) across time in people living with HIV, and how presenting averaged data hides this important variability. Our data support the reporting of individual-level data in human experimental and observational studies.

Randomized Controlled Trial
The effect of in-session exposure in Fear-Avoidance treatment of chronic low back pain: A randomized controlled trial.
Treatment based on the Fear-Avoidance (FA) model has been found to be effective with chronic low back pain (CLBP), and in-vivo exposure of fear evoking movements is proposed as a key change mechanism. Exposure tasks may be conducted in the session (in-session exposure; ISE), in other real-life situations (between sessions exposure) as part of homework assignments, or both. Utilising a randomized, controlled dismantling study design, the aim of this study was to examine the unique effects of ISE in FA-treatment of CLBP. ⋯ This study adds to the existing research literature demonstrating FA-treatment to be effective with CLBP, but further experimental studies are needed in order to examine under what circumstances ISE of feared movements may add to positive treatment outcomes.
