Impact of aging on long-term cardiac outcomes of true-lumen recanalized chronic total occlusions in patients with overweight/obesity.
Article in International journal of obesity (2005), 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundObesity paradox addressing all-cause mortality has been described in several chronic total occlusion (CTO) studies. However, the impact of aging on long-term cardiac events in patients with overweight and obesity with CTO recanalization were less studied.
methodsA total of 458 patients (64.4 ± 11.3 years, 403 male) with CTO interventions were enrolled. The overweight/obesity group included 311 patients with body mass index (BMI) ≧24 kg/m
resultsAt follow-up, the rates of cardiac death, TVMI, TLR, TLF, and stent thrombosis were 1.9%, 1.9%, 9.2%, 10.7%, and 0.5%, respectively. The TVMI-free survival was borderline better (p = 0.067 by log-rank test) in overweight/obesity than non-obesity group. Among patients <65 years of age, the TVMI-free survival was significantly better in the overweight/obesity group (p = 0.013 compared to non-obesity group by log-rank test). In multivariate Cox regression model, the non-obesity patients younger than 65 years were at a higher risk of TVMI, not only among those <65 years of age (hazard ratio = 11.0, 95% CI = 1.1-106.0) but also among the whole patients (hazard ratio=6.9, 95% CI = 1.4-35.1) with successful CTO recanalization.
conclusionsFor those with true-lumen recanalized CTO, the higher risk of TVMI after successful recanalization was rather evident in patients <65 years of age and without overweight/obesity, suggesting that aging might attenuate prognostic significance of "obesity paradox" for CTO interventions.
