Relationship between serum fibroblast growth factor-23 level and mortality in chronic hemodialysis patients.

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
backgroundFibroblast growth factor-23 (FGF23) is a phosphate-regulating hormone and is found to be markedly increased in patients with chronic kidney disease. The aim of the present study was to evaluate the relationship between serum FGF23 levels and mortality, including the impact of gender and cardiovascular disease (CVD), in a Japanese cohort of chronic hemodialysis (HD) patients.
methodsNinety-two maintenance dialysis patients (58 men; mean age 60.3 years) were included. Serum intact FGF23, calcium, phosphate, albumin, intact parathyroid hormone (PTH), and C-reactive protein were measured at baseline. CVD was defined as clinical symptoms and/or a history of CVD.
resultsDuring a median follow-up time of 53.2 months, 24 patients (26 %) died. Serum FGF23 levels were positively correlated with serum levels of calcium (r = 0.5433, P < 0.0001), phosphate (r = 0.5048, P < 0.0001), calcium × phosphate product (r = 0.6801, P < 0.0001), and intact PTH (r = 0.2710, P = 0.0090) (r = 0.27, P < 0.0001). In Cox proportional hazard models, serum FGF23 level was not associated with increased mortality risk, neither in crude nor in multivariate-adjusted models. However, in a subgroup analysis of women with previous CVD, serum FGF23 level above median was associated with higher cardiovascular event risk in crude models (hazard ratio 9.52, 95 % confidence interval 1.56-86.11, P = 0.0129). Kaplan-Meier analysis stratifying for the presence of CVD demonstrated a significant higher mortality risk in patients with history of CVD and higher serum FGF23 levels (P < 0.0001).
conclusionSerum FGF23 level was not associated with increased mortality risk in this cohort of prevalent HD patients. These results suggest that the impact of FGF23 on mortality may be modified by gender and previous CVD and is blunted in the grade of hyperphosphatemia.
