Prevalence of Frailty and Evaluation of Associated Variables Among COPD Patients.
Article in International journal of chronic obstructive pulmonary disease, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 20 papers, 5 of them syntheses that pooled 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.
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
Rationale: Frailty in chronic obstructive pulmonary disease (COPD) patients has been associated with a higher rate of incidents, longer duration of hospitalization, poorer quality of life, and higher mortality. Objective: To measure the prevalence of frailty among COPD patients and to evaluate associated variables. Methods: A cross-sectional study. Subjects who visited a State Center for High-Cost Medicines to obtain free monthly COPD medicines were considered eligible. Individuals ≥40 years old who had a FEV Results: The prevalence of frailty and pre-frailty among the 153 COPD subjects enrolled was 50.3% (77/153) and 35.3% (54/153), respectively. Frailty scores were correlated with CAT (correlation coefficient [cc]: 0.52, p <0.001) and MRC (cc: 0.48, p <0.001). Ordinal regression models showed that MRC and CAT were associated with fragility (p <0.0001 for both models). Higher odds of frailty were observed in GOLD groups B (p = 0.04) and D (p = 0.02). Multiple logistic regression revealed that the combination CAT/MRC≥5.5 was associated with frailty (OR 6.73; p <0.0001) and had a specificity of 80.3%, sensitivity of 62.3%, and positive and negative predictive values of 76.2% and67.8%, respectively. Conclusion: Frailty prevalence was high and was correlated with higher MRC and CAT scores. The CAT/MRC combination [(CAT/8)+MRC] ≥5.5 was highly associated with frailty, suggesting that an additional specific evaluation for the presence of frailty is indicated.
