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

backgroundSerum phosphate (P) levels are generally lower in autosomal dominant polycystic kidney disease (ADPKD) than in other kidney disorders, potentially masking the clinical significance of hyperphosphatemia. This study aimed to determine if serum P levels can predict renal outcomes in ADPKD patients.

methodsWe included 235 patients with ADPKD who were not taking drugs to treat hyperphosphatemia. Survival analysis was performed for the renal outcome of a 50% reduction in estimated glomerular filtration rate or initiation of renal replacement therapy.

resultsMultivariable Cox regression analyses revealed that serum P (1 mg/dL increase, HR = 2.03, P < 0.0001) was a significant risk factor for kidney disease progression. Similarly, hyperphosphatemia (P > 3.5 mg/dL, HR = 2.05; P > 4.0 mg/dL, HR = 1.90; P > 4.5 mg/dL, HR = 2.78; P > 5.0 mg/dL, HR = 27.22) was significantly associated with renal prognosis. Kaplan-Meier analysis showed significantly lower kidney survival rates in patients with P > 3.5 mg/dL than in those without hyperphosphatemia (log-rank test, P < 0.0001), and similar Kaplan-Meier analysis results were found for P > 4.0 mg/dL, P > 4.5 mg/dL, and P > 5.0 mg/dL. The 2 year kidney survival rate for ADPKD patients with P > 3.5 mg/dL was 66.7% overall and 41.4% in those with stage 4-5 CKD. For patients with P > 4.0 mg/dL, the survival rate dropped to 46.8% overall and 28.2% in those with stage 4-5 CKD, indicating a very poor prognosis.

conclusionHyperphosphatemia was associated with renal prognosis in patients with ADPKD. In these patients, attention should be paid to even mild serum P elevation of > 3.5 or > 4.0 mg/dL.
