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

objectivesThis study aimed to investigate the effects of long-term and habitual physical activity on mortality and long-term care insurance (LTCI) certification among cancer survivors using a population database.

design5-year retrospective study.

setting13 Japanese municipalities participated in the Longevity Improvement & Fair Evidence study.

participantsAmong 471 511 participants who underwent health check-ups, 39 435 met the following eligible criteria: documented in the cancer claims database without a suspected diagnosis and participated in a health check-up at least once in a 12-month period, had no missing exercise data and had already been certified for LTCI.

main outcome measuresOutcomes were new LTCI certification and all-cause mortality. LTCI certification was assigned by a trained local government official through a systematic process (involving various items-physical function, daily activity function, cognitive function, behavioural disorders, adjustment to social life and daily use of medical services-as well as overall consideration of computer-based and specialist team assessments), and the LTCI severity level correlates with the Barthel index. LTCI certification reflects some impairment in activities of daily living. All-cause mortality was defined based on claims data.

resultsThree physical activity categories, 'exercise and walking', 'exercise or walking' and 'no physical activity', were used. Among survivors aged 65-74 years, the 'no physical activity' group had a higher risk of mortality and LTCI certification than the 'exercise and walking' group (adjusted model HR: 1.72, 95% CI 1.52 to 1.94). Among survivors aged ≥75 years, the low physical activity groups had a higher risk of mortality and LTCI certification than the 'exercise and walking' group (adjusted model: 'exercise or walking', HR: 1.51, 95% CI 1.29 to 1.85; 'no physical activity', HR: 1.66, 95% CI 1.43 to 1.92). The effects of physical activity differed according to cancer type.

conclusionsHabitual physical activity had positive effects on cancer survivors. These effects differed according to age and cancer type.
