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
Background: Erectile dysfunction (ED) is a prevalent condition with significant psychological and physiological impacts. Recently, a new concept called movement-based behaviors (MBB) has been proposed, which includes four types of PA: vigorous PA (VPA), moderate-intensity PA (MPA), walking/cycling, and muscle-strengthening activities (MSA), and uses an MBB index (range 0-4) to estimate the combined effects of these activities on health outcomes. Aim: This study aims to evaluate the relationship between different types of physical activities (PA) and ED using the MBB index in a nationally representative sample of U.S. men. Methods: We analyzed data from the National Health and Nutrition Examination Survey (NHANES) 2001-2004, including 3435 male participants. Multivariate logistic regressions were performed to explore the associations, supplemented with subgroup analysis and sensitivity analysis. Outcomes: The assessment of PA in this study is based on four self-reported questions from the NHANES Mobile Examination Center interview, including VPA, MPA, walking/cycling, and MSA. The MBB index, ranging from 0 to 4, was used to assess combined PA types. ED was evaluated using a single-question self-assessment. Results: Higher MBB index values were associated with lower ED risk. Participants with an MBB index of 2 had a significantly lower risk of ED in Model 3 (OR = 0.65, 95% CI: 0.43-0.97, P = 0.04). Those with an MBB index of 3 or 4 had the lowest risk of ED across all models, with OR_Model1 = 0.29 (95% CI: 0.21-0.40, P < 0.0001), OR_Model2 = 0.52 (95% CI: 0.37-0.73, P < 0.001), and OR_Model3 = 0.61 (95% CI: 0.41-0.90, P = 0.02). However, this relationship was not significant in subgroups with severe ED or comorbid conditions. Clinical Implications: Our findings can provide clinicians with guidance to help patients personalize their selection of different exercise combinations. Strengths and Limitations: We explored the impact of different exercise combinations on reducing ED risk and innovatively proposed the MBB index for a comprehensive assessment of exercise benefits, supported by a large sample size and multivariable adjustments. However, the limitations of cross-sectional design and recall bias cannot be overlooked. Conclusion: The MBB index effectively demonstrates that combined PA can reduce ED risk, supporting tailored exercise recommendations for patients.
