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

backgroundMineral and bone disorder (MBD) is common and associated with mortality in patients with chronic kidney disease (CKD) Given that disarrays in serum phosphorus (P) and parathyroid hormone (PTH) levels and their changes over time are closely interrelated, modeling mortality-predictability of their combinations may help improve CKD patient management.

methodsA historical cohort study was undertaken to evaluate the joint effect of serum P and PTH levels on mortality in 107,299 chronic hemodialysis (HD) patients. Changes in serum P and PTH levels over 6months, in particular discordant changes, were also modeled with mortality.

resultsHD patients were 64±15 (mean±SD)years old and included 45% women, 33% African-American, and 59% diabetic. Compared with serum P level ≥7.0mg/dL and PTH level ≥600pg/mL, adjusted hazard ratio (HR) tended to be lowest in patients with serum P level of 3.5-<5.5mg/dL combined with PTH level of 150-<300pg/mL (HR 0.64, 95% confidence interval 0.61-0.67). A change over time in serum P level towards the 3.5-<5.5mg/dL range from higher or lower ranges was associated with a decreased mortality, whereas only change in PTH level from <150pg/mL to 150-<300pg/mL range was associated with a lower risk of mortality. Upon discordant changes of PTH and P, i.e., decrease in one of the two measures while the other increased, no change in mortality risk was observed.

conclusionIn CKD-MBD management, patent survival is the greatest with controlling both serum P and PTH levels in balance. Tailoring an individualized treatment strategy in CKD-MBD may benefit patients. Further studies are needed.
