Relationship Between Cardiac Autonomic Control and Intradialytic Hypotension in Senegalese Chronic Hemodialysis Patients: A Single Center Prospective Study.
Article in Electrolyte & blood pressure : E & BP, 2025. 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: Intradialytic hypotension (IDH) increases cardiovascular morbidity and mortality in chronic hemodialysis patients and cardiac autonomous neuropathy (CAN) might be involved. To assess cardiac autonomic control in hemodialysis patients and describe its relationship with IDH. Methods: We conducted a prospective study at Ouakam Military Hospital in Senegal from January 1st to March 31st, 2023. Fifty-two patients (31 men, mean age 47.54 years) were included and had 3 measurements of heart rate variability (HRV): before, during and after an index hemodialysis session. They were classified according to changes in systolic blood pressure (SBP) during hemodialysis into three groups: 14 patients in group I (increase > 10 mmHg in mean intradialytic SBP), 13 in group II (decrease ≥ 20 mmHg in mean intradialytic SBP or MAP > 10 mmHg) and 25 in group III (others). HRV frequency domain indices between groups were compared. Results: In pre-dialysis, patients in group II showed higher values in total power (650.30 vs. 94.94 and 108.11 ms Conclusion: Our results found that HRV was similar between patients with and without IDH suggesting the influence of other risk factors that need to be explored in further studies.
