Clinical outcomes of fasting in patients with chronic heart failure with preserved ejection fraction: A prospective analysis.
Article in Annals of medicine and surgery (2012), 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis that pooled 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.
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
Fasting is a part of many world religions and in Islam fasting is obligatory for every adult Muslim during the month of Ramadan. Islam has exempted sick people from fasting; however, many people still partake in this activity. We investigated how Islamic fasting affects patients with heart failure with preserved ejection fraction (HFpEF). We enrolled 938 patients (fasting n = 456; non-fasting = 482) in this prospective observational study. The fasting group showed a decrease in NYHA functional class III (23.36% vs. 17.77%; p-value < 0.05) and IV (3.76% vs. 2.19%; p-value < 0.05), and an increase in class I(35.57% vs. 43.64%; p-value < 0.05). symptoms. This is an important area for physicians to advise patients with HFpEF to fast in the month of Ramadan as it can have a favorable effect on their symptoms and quality of life.
