[Association between cardiorespiratory fitness and mortality risk in the chilean population].
Article in Revista espanola de salud publica, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveCardiorespiratory fitness reduces the risk of cardiometabolic diseases, cancer and mortality. The aim of this paper was to evaluate the relationship between equation-estimated cardiorespiratory fitness and all-cause mortality in the Chilean population of both genders according to data from the 2009-2010 National Health Survey (NHS).
methodsData from 4,749 participants from the 2009-2010 NHS were analysed after 10.9 years of follow-up. Fitness was estimated with the Myers et al. equation and classified into quintiles. All-cause mortality records were obtained from the Chilean Civil Registry and Identification until 2020. Cox regression models adjusted for confounding variables (demographics, nutritional status, lifestyle and comorbidities) were used to assess the association between fitness and mortality.
resultsDuring the 10.9 years (IQR: 10.8; 11.4) of follow-up 506 (10.6%) people died. Compared to the lowest fitness quintile (<7 METs) those classified in the highest quintile (>12 METs) had a 95% lower risk of mortality (HR: 0.05; 95% CI: 0.03, 0.09) and the risk of mortality was 28% lower for every 1-METs increase in fitness (HR: 0.72 95% CI: 0.69, 0.75). All these associations were independent of confounders.
conclusionsWe conclude that a higher level of fitness is associated with a lower risk of mortality independent of confounding factors in the Chilean population after 10.9 years of follow-up.
