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

backgroundThe optimal surgical approach for patients with primary hyperparathyroidism (pHPT) and multiple endocrine neoplasia 1 (MEN1) is controversial. We sought to determine the optimal type of surgery for pHPT in MEN1.

methodsWe collected data on clinical presentation, surgery, and follow-up for MEN1 patients with pHPT at the University Medical Center Utrecht and affiliated hospitals between 1967 and 2008. Furthermore, we performed a systematic review of the literature and meta-analysis. Surgical procedures were classified into less than subtotal (<SPTX) versus subtotal (SPTX) and total parathyroidectomy (TPTX).

resultsFifty-two patients underwent primary surgery for pHPT, of which 29 had <SPTX, 17 SPTX, and 6 TPTX. Recurrent pHPT was most frequent after SPTX (65%) followed by <SPTX (59%). Persistent disease was most frequent after <SPTX (31%). Time to recurrence was 61 months longer after SPTX than after <SPTX. Although recurrent pHPT was not seen after TPTX, permanent hypoparathyroidism developed in 67% of these patients. The meta-analysis showed that after SPTX and TPTX, patients had the lowest risk of persistent and recurrent pHPT. TPTX had the highest risk of permanent hypoparathyroidism. Large noncomparative studies showed a low recurrence rate after SPTX and TPTX.

conclusionWe believe that SPTX is the best surgical therapy for pHPT in MEN1. MEN1 patients with pHPT should not be treated with <SPTX because of the unacceptable high rate of recurrent and persistent pHPT. Additionally, a thymectomy should routinely be performed in these patients.
