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

Non-transfusion-dependent thalassaemia (NTDT) is associated with chronic health problems. A cross-sectional study was conducted in Hong Kong Chinese patients to evaluate the presentation and complications of NTDT. One hundred and nine patients aged between 6.7 and 72.3 years (median: 32 years), including 97 with α-thalassaemia intermedia and 12 with β-thalassaemia intermedia, were included from two public hospitals. Among them, 82% had never been transfused and 18% had received sporadic transfusions. Chelation therapy had been given to 7% of patients. Notably, 52% of patients had chronic health deficits with a strong positive correlation with advanced age, log-transformed ferritin levels and history of splenectomy. Hepatic iron overload was detected in 43% of patients, and extramedullary haematopoiesis in 14%. At least one endocrinopathy developed in 12% of patients. Patients with non-deletional α-thalassaemia intermedia and β-thalassaemia intermedia exhibited more severe disease than those with deletional α-thalassaemia intermedia. This study highlighted the need for ongoing monitoring and management strategies for NTDT to mitigate chronic health issues and improve outcomes.
