Assessment of Left Atrial Strain in Patients with and without Chronic Obstructive Airway Disease.
Article in Journal of cardiovascular echography. 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
Background: The cardiac abnormality related with chronic obstructive pulmonary disease (COPD) has traditionally been right ventricular (RV) dysfunction, publications in the last century already reporting pathological left atrial (LA) changes due to increased (LV) end diastolic pressure which increases the LA strain. Aim: To evaluate left atrium (LA) strain by two-dimensional (2D)- STE in patients with chronic obstructive pulmonary disease (COPD). Patients and Methods: This prospective study was carried out on 39 subjects divided into (Group I) including 14 normal persons and (Group II) including 25 COPD patients with typical symptoms and signs and typical radiological features of COPD. All subjects were subjected to resting transthoracic echocardiography and left atrial strain analysis. Results: Left atrium, aorta, pulmonary artery systolic pressure (PASP), E/A were significantly higher in group 2 than group left atrial strain rate (LA sr) (apical 4 and 2 chamber) were significantly higher in group 1 than group 2 ( Conclusions: LA sr was affected in COPD patients.
