Clinical and Echocardiographic Characteristics of Neuroendocrine Tumours and Carcinoid Heart Disease: Insights from a Contemporary Canadian Cohort.
Article in CJC open, 2026. 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: Neuroendocrine tumours (NETs) are uncommon cancers that secrete vasoactive hormones. Around half of those with metastatic small bowel NETs develop carcinoid syndrome, and historically, up to 50% develop carcinoid heart disease (CHD). We evaluated clinical characteristics, echocardiographic features, and outcomes of patients with NETs and CHD in a contemporary cohort to identify factors associated with CHD development and mortality. Methods: We identified patients with NETs who underwent an echocardiogram at a tertiary cancer centre-affiliated laboratory (2013-2023). Patients were classified based on whether they developed CHD. Clinical characteristics, echocardiographic data within 6 months of NET diagnosis, treatments, and outcomes were compared between CHD and non-CHD patients. Results: Over a 10-year period, 87 patients with NETs were identified (48% female; median age, 61 years), with 18 (21%) developing CHD. Primary small bowel NETs were more common with CHD (83% vs 55%, Conclusions: Within a contemporary cohort, approximately 1 in 5 patients with NETs develop CHD and exhibit only right-sided valve involvement. CHD was associated with increased mortality whereas primary NET resection was associated with improved survival.
