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

In individuals with advanced chronic kidney disease, secondary hyperparathyroidism is known to be associated with high turnover bone disease. Low serum parathyroid hormone (PTH) levels may not necessarily be because of hypodynamic bone, but could be another facet of the malnutrition-inflammation-cachexia syndrome (MICS). A recent 5-year cohort study in 748 stable hemodialysis outpatients showed that after the confounding effect by the MICS was removed, the moderately low levels of PTH in the 100 to 150 pg/mL range was associated with the greatest survival rate. Data from Japanese dialysis patients show similar survival advantages of having a lower PTH range. Low levels of serum PTH seem to be associated with markers of protein-energy wasting and inflammation, and this association may confound the relationship between serum PTH and alkaline phosphatase. PTH stimulates lipogenesis through influx of calcium into the adipocytes. PTH secretion is suppressed by interleukin-1 beta and interleukin-6, which are proinflammatory cytokines that are associated with poor outcome in dialysis patients. These cytokines inhibits PTH secretion in cultured parathyroid tissue slices. In this article, we review the association of a low serum PTH level with the MICS in patients with chronic kidney disease and suggest avoiding over-interpretation of low serum PTH level as an indicator of low turnover bone disease.
