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.
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
backgroundAlthough higher pre-diagnosis physical activity is linked to lower mortality among cancer survivors, it is unclear whether this is due to a reduced likelihood of metastatic cancer at diagnosis. This study evaluated whether adherence to physical activity guidelines before diagnosis is associated with all-cause mortality and metastatic cancer at diagnosis.
methodsIn the prospective Lifelines Cohort Study of 152,915 adults, we identified individuals diagnosed with primary cancer at any site through linkage to the Netherlands Cancer Registry. Adherence to physical activity guidelines was defined as ≥150 minutes of moderate-intensity activity, ≥75 minutes of vigorous-intensity activity, or an equivalent combination per week. Cox and logistic regression estimated adjusted HRs and ORs with 95% confidence intervals (CI) for associations between adherence to physical activity guidelines, all-cause mortality, and metastatic cancer at diagnosis.
resultsA total of 5,990 patients with cancer were included: 10.7% reported no physical activity, 19.1% were insufficiently active, and 70.2% were sufficiently active. Patients with cancer adhering to physical activity guidelines had a 16% lower risk of all-cause mortality compared with those who reported no physical activity (HR = 0.84; 95% CI, 0.72-0.98). However, meeting physical activity guidelines was not significantly associated with a reduced likelihood of metastatic cancer at diagnosis (OR = 0.98; 95% CI, 0.79-1.23).
conclusionsPhysical activity at recommended levels before cancer diagnosis is linked to reduced mortality among cancer survivors, independent of metastatic cancer at diagnosis. IMPACT: These findings highlight the beneficial role of physical activity in reducing mortality in patients with cancer.
