1 · What the graph read from it

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.

2 · The registry

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

backgroundBiological sex plays a role in systemic features of patients with Chronic Obstructive Pulmonary Disease (COPD). We investigated whether male and female COPD patients show distinct trajectories in muscle and brain health decline during aging.

methodsIn total 228 patients (age >50 years) with stable COPD (GOLD: II-IV) were stratified into four groups based on their sex and age (50-70 years vs ≥70 years). Body composition (DXA), muscle strength (dynamometry), cognitive function and well-being (assessments and questionnaires), and risk factors of poor systemic health were analyzed in these groups.

resultsBody weight and lean mass remain unchanged with aging. The ≥70 years males showed higher visceral adipose tissue and lower muscle strength whereas females showed lower fat mass and fat-free mass index, and worse cognitive performance compared with their younger counterparts (P < 0.04). In males, lower physical activity was associated with higher visceral adipose tissue and lower muscle function, whereas poor cognition was associated with low O

conclusionAging in male COPD patients is characterized by metabolic syndrome features and muscle weakness whereas aging in female COPD patients is associated with weight loss, sarcopenia, and cognitive decline. The observed systemic changes were influenced by different combinations of risk factors in male and female COPD patients. Our findings indicate that sex-specific therapies need to be considered when treating older patients with COPD.
