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

contextThe distinctive presentation of primary hyperparathyroidism (PHPT) in adults and youths suggest that PHPT is a fundamentally different disease in these two groups.

objectiveTo understand the difference in PHPT between adults and youths we compared the biochemistry of PHPT in these two groups.

designThis study is a systematic review and meta-analysis of retrospective studies published 1966-2014 on PHPT. DATA SOURCES: All studies were obtained through Medline (1966-2014). STUDY SELECTION AND DATA EXTRACTION: Only studies that included post-surgical subjects and that explicitly described biochemical results from more than one decade were included. Data were extracted from each article to generate the mean and SE for multiple biochemical parameters. DATA SYNTHESIS: We analyzed 16 studies describing 268 unique youths and 2405 adults with PHPT. Youths with PHPT had significantly (P < .05) greater serum and urinary calcium than adults with PHPT (3.2 ± 0.1 mmol/L vs 2.8 ± 0.0 mmol/L for serum calcium, and 9.95 ± 1.26 mmol/d vs 7.15 ± 0.56 mmol/d for urine calcium, [mean ± SEM]). There were no significant differences in serum intact PTH, phosphorus, or alkaline phosphatase.

conclusionsJuvenile PHPT has greater hypercalcemia and hypercalciuria than adult PHPT at similar concentrations of serum intact PTH. These observations suggest that there are differences in the pathophysiology of PHPT between juvenile and adult patients who reflect an apparent decrease in the sensitivity of the parathyroid adenoma to negative feedback by calcium and increased sensitivity of target tissues to the effects of PTH.
