1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

purposeAndrogen deprivation therapy (ADT) for prostate cancer adversely affects quality of life. Whilst exercise is effective for ameliorating many side effects, most people are inactive, with lack of motivation a key barrier. Self-determination theory (SDT) specifies the quality, rather than quantity, of motivation as essential for optimal engagement. We aimed to explore exercise motivation in men on ADT through the theoretical lens of SDT.

methodsAs part of a mixed-method longitudinal study, semi-structured interviews exploring exercise behaviour and perceptions, were conducted with people receiving ADT for prostate cancer. Thematic analysis identified motivation themes aligned with SDT concepts.

resultsTwenty-four men participated (median age 74 years; ECOG 0: 92%, metastatic: 29%). We identified two key themes: (1) type of exercise motivation and (2) use of need-supportive techniques in exercise environments. Motivations ranged from intrinsic (for enjoyment) to external (compliance with other's expectations). Key strategies to support psychological needs included offering choice in exercise programming, providing meaningful rationales for exercise, tailored guidance from exercise professionals, and social support.

conclusionsThis SDT-grounded study provides insights into motivations driving exercise in people receiving ADT and how social and healthcare contexts influence these motivations. The study underscores the importance of considering exercise motivation when discussing, referring, and designing tailored exercise interventions to ensure they are need-supportive to optimise engagement. IMPLICATIONS FOR CANCER SURVIVORS: This study highlights the importance of exercise interventions that are supportive of psychological needs. Incorporating need-supportive strategies may enhance exercise participation and improve physical and psychosocial outcomes for men receiving ADT.
