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

purposeExercise and healthy diet are key components of cancer survivorship. We sought to explore perceived barriers to engaging in healthy diet and exercise, and whether these barriers change throughout remote-based behavioral interventions.

methodsSmart Pace (SP) and Prostate 8 (P8) were two 12-week pilot randomized controlled trials (RCTs) among 42 colorectal cancer (CRC) survivors and 76 prostate cancer (PC) survivors, respectively, that encouraged participants to implement exercise (both) and healthy diet (P8 only) through text messaging and wearable fitness monitors; P8 also included web materials. Participants completed surveys on perceived barriers and confidence in their ability to implement healthy behaviors at enrollment and 12 weeks; P8 also included a 52-week assessment.

resultsAt enrollment, CRC survivors commonly reported a lack of discipline/willpower (36%), time (33%), and energy (31%); PC survivors often reported a lack of knowledge about healthy dietary behaviors (26%). Not having anyone with whom to exercise with was a common barrier among both groups (21% in CRC, 20% in PC). Among the intervention groups in both studies, various enrollment barriers (overall, functional/psychological disability, aversiveness, excuses, and inconveniences) were associated with change in behavior over time.

conclusionsAmong CRC and PC survivors, there are multiple potential barriers related to motivation, time, social support, and lack of knowledge, that can be addressed and overcome to improve healthy behaviors. Tailoring lifestyle interventions to participants' individual barriers and confidence is needed to promote and sustain behavior change long-term.
