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

purposeTo examine the association of physical activity among long-term breast cancer survivors on the occurrence of subsequent cardiovascular disease (CVD).

methodsWe investigated the risk of CVD among 39,775 breast cancer patients who were newly diagnosed in 2006 and survived until 2011 within the Korean National Health Insurance Service database. Patients were followed up from 5 years after breast cancer diagnosis to the date of CVD event, death, or December 31, 2018, whichever came earliest. Every 500 MET-mins/week correspond to 152, 125, and 62.5 min per week of light-, moderate-, and vigorous-intensity physical activity, respectively. Adjusted hazard ratios (aHRs) and 95% confidence intervals (CIs) for CVD were calculated using Cox proportional hazards regression by physical activity levels.

resultsCompared with those with physical activity of 0 MET-min/week, those with 1-499 (aHR 0.82, 95% CI 0.69-0.98), 500-999 (aHR 0.75, 95% CI 0.63-0.90), and ≥ 1,000 (aHR 0.76, 95% CI 0.63-0.93) MET-min/week of PA had lower risk of CVD. Higher levels of PA were associated with lower risk of stroke (p for trend = 0.016). The benefits of PA on obese and overweight breast cancer survivors were smaller than those in normal weight survivors. The frequency of moderate-to-vigorous physical activity (MVPA) showed a reverse J-curve association with CVD, and the best benefit occurred in the 3-4 times MVPA per week group (aHR 0.59, 95% CI 0.46-0.74).

conclusionsThe study showed that even small amounts of PA may be beneficial in potentially decreasing the risk of CVD, CHD, and stroke in breast cancer survivors. Our result will be useful to prescribe and delivery exercise among long-term breast cancer survivors.
