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

The diagnostic performance of positron emission tomography using ¹¹C-methionine (MET-PET) in detecting parathyroid adenoma has been investigated by several studies with conflicting results. Aim of our study is to meta-analyze published data about this topic. A comprehensive computer literature search of studies published in PubMed/MEDLINE, Scopus and Embase databases through May 2012 and regarding the diagnostic performance of MET-PET in patients with parathyroid adenoma was carried out. No language restriction was used. Only articles in which at least five patients with parathyroid adenoma underwent MET-PET were included in the meta-analysis. Pooled sensitivity and detection rate (DR) on a per patient-based analysis were calculated to assess the diagnostic performance of MET-PET. Nine studies comprising 258 patients with suspected parathyroid adenoma were included in this meta-analysis. Pooled sensitivity and DR values of MET-PET in patients with suspected parathyroid adenoma were 81 % (95 % confidence interval [95 %CI] 74-86 %) and 70 % (95 %CI 62-77 %), respectively, on a per patient-based analysis. The included studies were heterogeneous in their estimate of sensitivity and DR. Our meta-analysis demonstrates that MET-PET is a sensitive and reliable tool in patients with suspected parathyroid adenoma. Thus, this imaging method could be helpful in patients with diagnosis of primary hyperparathyroidism when conventional imaging techniques are negative or inconclusive in localizing parathyroid adenoma.
