Efficacy of L-methylfolate and methylcobalamin in treating resistant hypertension associated with elevated serum homocysteine in hemodialysis patients.
Trial report in BMC nephrology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05807711 (Efficacy of L-methylfolate and Methylcobalamine in Treating Resistant Hypertension Associated With Elevated Serum Homocysteine in Hemodialysis Patients.), which is not on this 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.

Abstract
backgroundEnd-stage renal disease (ESRD) patients receiving hemodialysis are experiencing a considerable increase in the burden of cardiovascular diseases (CVDs). In this patient population, hypertension is a prevalent modifiable cardiovascular risk factor that is associated with poor prognosis. Resistant hypertension in dialysis patients is challenging to manage since some individuals do not respond to antihypertensive medications or volume control. Hyperhomocysteinemia is common among ESRD patients. "H-type hypertension" or hyperhomocysteinemia-associated hypertension refers to resistant hypertension with elevated cardiovascular risk. The current study examined the efficacy of methylfolate and methylcobalamin supplementation in reducing serum homocysteine levels and improving blood pressure (BP) control in ESRD patients with resistant hypertension on regular hemodialysis.
methodsThroughout the study, 51 ESRD patients with resistant hypertension were randomly allocated to receive either daily doses of L-methylfolate 800 mcg and methylcobalamin 1000 mcg capsule (intervention group) or no medication (control group). Serum homocysteine levels were measured twice: at baseline and three months later. In addition, average pre- and post-dialysis blood pressure readings were obtained at baseline, one month, two months, and three months.
resultsAfter three months, mean serum homocysteine levels were significantly lower than at the commencement of therapy (p = 0.035), nonetheless, control patients showed no significant difference. Between-group analysis found a statistically significant difference in the change in homocysteine levels among the two groups (p = 0.006). Furthermore, the treatment group had statistically significant lower pre- and post-dialysis blood pressure readings.
conclusionsA three-month supplementation with a combination of 800 mcg methylfolate and 1000 mcg methylcobalamin showed promise in lowering blood pressure and serum homocysteine levels in ESRD patients with resistant hypertension. These findings require additional exploration in larger studies.
