Serum Vitamin B12 Deficiency in Chronic Hemodialysis Patients.
Article in Cureus, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Introduction Essential vitamins like folate and vitamin B12 are crucial for many physiological functions. Patients with renal failure undergoing regular hemodialysis in the general population may experience harmful effects from vitamin B12 deficits. Therefore, this study aimed to determine the frequency of vitamin B12 deficiency in hemodialysis patients and its association with other clinical parameters. Methods This cross-sectional study was conducted at the dialysis unit of Patel Hospital and Lifeline Hospital, Karachi, using a non-probability consecutive sampling technique after obtaining ethical approval from Lifeline Hospital (LLH/HR/02-22). The study duration was six months, from January 10, 2023, to July 22, 2023. A total of 135 adult renal failure patients with ages >18 and <70 years on maintenance hemodialysis for >1 year were included in the study. The chi-square test was used to determine the association between vitamin B12 deficiency and age and gender. A p-value of 0.05 was considered statistically significant. Results The study findings showed that out of 135 patients, 82 (60.7%) were males and 53 (39.3%) were females, with a mean age of 50.80 ± 10.03 years. The duration of hemodialysis was approximately 1-2 years in 98 (72.6%) patients, 2-3 years in 27 (20.0%) patients, and 3-4 years in only 9 (6.7%) patients. The mean serum vitamin B-12 levels were 411.61 ± 224.95 pg/ml, with 30 (22.2%) of the subjects being deficient. In terms of duration of hemodialysis, there was a significant association (p= 0.013). Between patients with normal 4 (4%) and deficient 5 (17%) vitamin B12 and 3-4 years of hemodialysis. Conclusion In this study, we found that a significant proportion of patients on chronic hemodialysis had vitamin B12 deficiency. Moreover, vitamin B12 deficiency was significantly associated with duration of hemodialysis. Therefore, we recommend periodic vitamin B12 testing in hemodialysis patients to avoid any associated complications.
