1 · What the graph read from it

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.

2 · The registry

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

backgroundThis meta-analysis aims to investigate the impact of abnormalities in mineral metabolic markers, including serum phosphate and calcium, intact parathyroid hormone (iPTH), and fibroblast growth factor 23 (FGF23) on the risk of fractures in patients with chronic kidney disease (CKD).

methodsA systematic search was conducted across MEDLINE, Web of Science, EMBASE, ClinicalTrials.gov, and the Cochrane Central Register for Controlled Trials. The outcomes were association of mineral metabolic markers with the risk of fractures in patients with chronic kidney disease. Pooled risk estimates and 95% confidence intervals (CIs) were calculated using fixed-effects or random-effects models.

resultsThirty-two studies were included in the meta-analysis. High and low levels of serum phosphate in hemodialysis (HD) patients were both associated with an increased risk of fractures (RR = 1.08, 95% CI 1.02-1.15, P = 0.013; RR = 1.13, 95% CI 1.02-1.25, P = 0.022, respectively). Similarly, abnormal levels of iPTH in CKD patients, both high and low, were associated with increased fracture risk (RR = 1.25, 95% CI 1.20-1.31, P < 0.001; RR = 1.41, 95% CI 1.10-1.82, P = 0.007, respectively). Elevated FGF23 levels were also linked to an increased risk of fractures (RR = 1.32, 95% CI 1.06-1.66, P = 0.015). While a higher level of calcium exhibited a trend towards reduced fracture incidence without statistical significance (RR = 0.90, 95% CI 0.77-1.05, P = 0.181), lower calcium levels tended to increase fracture risk without statistical significance (RR = 1.11, 95% CI 0.99-1.24, P = 0.087). Notably, subjects treated with calcium and phosphorus modulating drugs demonstrated a statistically significant reduction in fractures among CKD patients undergoing dialysis (phosphate binders, RR = 0.79, 95% CI 0.70-0.89; cinacalcet, RR = 0.74, 95% CI 0.59-0.93; vitamin D analogues, RR = 0.82, 95% CI 0.74-0.92, respectively).

conclusionThis meta-analysis underscores the association between abnormal mineral metabolic markers, including high serum phosphate, iPTH, and FGF23, and an increased risk of fractures in CKD patients. Notably, both elevated and decreased levels of phosphate and iPTH contribute to fracture risk. The efficacy of active vitamin D, phosphorus binders, and cinacalcet in preventing fractures was observed in HD patients but not in the non-dialysis CKD population.
