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
Objectives: This study examined the associations of different physical activity patterns with mortality risk and life expectancy among individuals with cardiometabolic multimorbidity (CMM). Design: We analyzed data from adults with CMM in the National Health Interview Survey (1997-2018), linked to mortality records through December 31, 2019. CMM was defined as the coexistence of at least two of heart disease, diabetes, and stroke. Methods: Physical activity was categorized as Inactive, Insufficiently Active, Weekend Warrior (≥150 min/week in 1-2 sessions), or Regularly Active (≥150 min/week in ≥3 sessions). Relative mortality risks were estimated using Cox proportional hazards models, absolute mortality rate differences using Poisson regression, and differences in life expectancy at ages 45 and 65 using flexible parametric survival models. Subgroup and sensitivity analyses assessed robustness. Results: The analytic sample included 15,079 adults with CMM, of whom 8299 (55.0%) were women. Over a mean follow-up of 10.1 years, 6932 deaths occurred. Compared with Inactive participants, mortality risk was 19% lower among the Insufficiently Active (HR = 0.81, 95% CI: 0.75-0.89), 36% lower among Weekend Warriors (HR = 0.64, 95% CI: 0.49-0.83), and 40% lower among the Regularly Active (HR = 0.60, 95% CI: 0.55-0.65). At age 45, estimated differences in life expectancy were 2.24, 4.60, and 4.94 years across these groups, respectively; corresponding differences at age 65 were 1.46, 3.04, and 3.27 years. Conclusions: Among individuals with CMM, recommended levels of physical activity, whether accumulated in 1-2 weekly sessions or more frequent exercise, were associated with lower mortality risk and longer life expectancy. Weekend Warrior and regular activity patterns showed comparable associations with survival-related outcomes.
