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

introductionRenal transplant patients are unique in that bone changes occur on a background of pre-existing chronic kidney disease-mineral bone disorder. In a few cases, there is overt hyperparathyroidism manifested by hypercalcaemia. Traditionally, if severe or persistent, this is treated by parathyroidectomy. At our unit, the default surgical operation is total parathyroidectomy without autotransplantation.

methodsPatient charts for the last three decades were reviewed retrospectively. Twenty-six subjects with functioning renal transplants who underwent parathyroidectomy had biochemistry and clinical information for at least 6 months pre- and post-surgery. The criteria for parathyroidectomy were persistent hypercalcaemia (>2.75 mmol/L) and/or clinical problems (e.g. kidney stones). A 5-year follow-up was available for all 26 subjects and a 9-year follow-up for 20 patients.

resultsAfter surgery, patients were supplemented with 1-α-calcidol. The median preoperative calcium level was 3.10 mmol/L. One month postoperatively, this fell to 2.41 mmol/L. Normocalcaemia was maintained at 5 years (2.40 mmol/L) and at 9 years (2.39 mmol/L), with a calcium-phosphate product of 3.0 mmol(2)/L(2) and median parathyroid hormone level of 12 pg/mL.

conclusionTotal parathyroidectomy without autotransplantation in renal transplant patients appears to be protective against persistent and recurrent disease. This is the largest series with the longest follow-up available in the literature of this specific patient population.
