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

backgroundHeart diseases due to iron overload are still the main cause of mortality in patients affected by beta-thalassemia. Detection of cardiac iron overload in pre-clinical stage allows tailoring of chelation therapy and follow-up strategies. Echocardiographic longitudinal strain analysis may be a useful tool for early detection of cardiac functional impairment iron-related.

methodsWe examined 58 patients with beta-thalassemia on regular blood transfusion and iron chelation, without overt cardiac disease who had recent Biosusceptometry SQUID to quantify liver iron concentration and cardiac assessment by CMR T2*.

resultsAverage global longitudinal strain (GLS) was able to identify abnormal (<20 ms) cardiac T2* values with 96% specificity and negative predictive value of 92% (AUC 0.84, P=0.01). Apical 4-ch GLS may help identify early longitudinal impairment associated with severe liver iron overload with 96% specificity and negative predictive value of 92% (AUC 0.84, P=0.02). Patients with severe liver iron overload had lower average Global Longitudinal Strain values compared to other patients (

conclusionGLS was a sensitive marker to detect both myocardial and liver iron overload in a population that is still free from cardiac symptoms. Thus, strain echocardiography may be a useful tool for early detection of iron overload in Beta-thalassemia.
