The Effect of 6 Months of Dietary Counselling on Sleep Outcomes Among Patients With Cardiovascular Diseases: A Randomised Controlled Trial.
Trial report in Journal of sleep research, 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
Sleep problems are highly prevalent among patients with cardiovascular diseases (CVD). We examined the effect of dietary counselling on sleep outcomes among patients with CVD. We performed secondary analyses within a previously conducted six-month randomised controlled trial among patients with CVD. Within the trial, the intervention group received dietary counselling aimed to increase adherence to the Dutch dietary guidelines and the control group received usual care. Diet quality was assessed with an index, in which higher scores (range 0-160) indicated better adherence. Sleep outcomes were assessed with the Pittsburgh Sleep Quality Index. An overall score > 5 was classified as a poor sleep quality. Among the 112 patients with CVD included in these analyses (68.9 ± 9.2 years; 74% male; 27.7 ± 4.0 kg/m
