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

backgroundIn April 2015, five types of phosphate binders (PBs) were available by prescription in Japan, namely calcium carbonate, sevelamer hydrochloride, lanthanum carbonate, bixalomer, and ferric citrate hydrate (FeC). FeC reduces serum phosphorus levels and increases the body's iron stores. However, it is unclear whether FeC lowers serum phosphorus relative to other agents in a regional practical setting.

methodsWe performed a retrospective observational cohort study of regional hemodialysis surveillance in the western Saitama area of Japan, which included 1374 hemodialysis patients enrolled from 32 satellite dialysis units. The clinical data and prescribing information were retrospectively collected and analyzed. The difference in serum phosphorus among the groups administered five types of PBs (new or additional) from April to September 2015 was the primary outcome.

resultsAs of April 2015, the median values of serum phosphorus, corrected calcium, and intact parathyroid hormone were 5.4 mg/dL, 9.1 mg/dL, and 147 pg/dL, respectively (N = 1374). Unexpectedly, with an increase in the number of PBs administered, serum phosphorous levels increased (p < 0.001). The significant changes in the serum phosphorus and hemoglobin levels were associated with the prescription of FeC but not with that of the other PBs.

conclusionsThis regional survey suggests that serum phosphorus is well managed and that FeC has the potential to reduce the serum phosphorus level relative to other PBs and to ameliorates anemia.
