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

backgroundVitamin D deficiency may contribute to osteoporosis in nephrotic syndrome (NS).

methodsA cross-sectional case-control study was performed to investigate 25 hydroxycholecalciferol [25(OH)D] status in 40 patients with NS in remission and 40 healthy controls. Serum levels of 25(OH)D, calcium, phosphate, alkaline phosphatase (ALP), and intact parathyroid hormone (PTH) were assayed. NS patients were segregated by age at onset, current age, type and duration of NS, months since relapse and current drug therapy.

resultsLevels of 25(OH)D showed a positive correlation with months elapsed since last NS relapse (r s = +0.4, p = 0.012) and were lower in NS patients within 3 months of relapse but similar to that of controls in patients in remission for >3 months [median 14.23 (interquartile range 12.19-17.63) vs. 19.75 (14.04-28.38) ng/ml, respectively; p = 0.039]. There was no correlation of 25(OH)D levels with other disease characteristics or drug therapy. ALP levels were also lowest after relapse (r s = +0.34, p = 0.036). Overall, 25(OH)D levels of <20 ng/ml occurred in 62.5 % of NS patients + controls, and correlated negatively with age (r s = -0.24, p = 0.037) but showed no significant correlation with calcium, phosphate, or PTH levels.

conclusionsIn our patients with NS, vitamin D stores remained low for 3 months after NS relapse but showed an increase with longer remission time to control levels. Vitamin D stores were not influenced by disease characteristics or therapy. Longitudinal studies are required to confirm these findings and evaluate the effect of vitamin D on bones, particularly in frequent relapsers.
