Association of serum folate concentrations with cancer mortality among patients with arthritis: a prospective cohort study.
Article in BMC public health, 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
backgroundPatients with arthritis exhibit abnormal serum folate concentrations and have a higher incidence of cancer. The aim of this study was to investigate the association of serum folate concentrations with cancer mortality among individuals with arthritis.
methodsThis cohort study included 7,514 patients with arthritis from National Health and Nutrition Examination Survey (NHANES) 1999 to 2016 and NHANES III (1988-1994). Death outcomes were ascertained by linkage to National Death Index records through 31 December 2019. Serum folate concentrations were categorized into 4 groups, group 1 (≤ 17 nmol/L); group 2 (17-≤34 nmol/L); group 3 (34-≤51 nmol/L); and group 4 (> 51 nmol/L). Cox regression models were used to calculate hazard ratios and 95% confidence intervals for the associations between folate concentrations and the risk of mortality.
resultsDuring a median follow-up of 9.75 [interquartile range, IQR, 5.75-14.5] years, there were 2,602 all-cause deaths, 949 deaths due to cardiovascular disease, and 478 deaths due to cancer. A non-linear association was observed for folate concentrations with the risk of cancer mortality (P < 0.001) among arthritis patients. Compared with the reference group 2, the hazard ratios for cancer mortality were 1.75 (95% CI, 1.15-2.69) in group 1, 1.70 (95% CI, 1.17-2.46) in group 3, and 1.60 (95% CI, 1.13-2.25) in group 4.
conclusionsThis study shows that both low and high levels of serum folate are associated with an increased risk of cancer mortality among individuals with arthritis, indicating a potential beneficial role of maintaining moderate serum folate concentrations in decreasing the risk of cancer mortality among this population.
