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 symptoms of muscle weakness, bone pain and fragility fractures can be an indication of osteomalacia. Phosphate is often not considered within osteologic parameters, decreased levels are therefore easily overseen. The additional test for fibroblast growth factor 23 (FGF23) as indicator for tumor-induced osteomalacia (TIO) is still largely unfamiliar.

objectiveBy emphasizing the role of phosphate and furthermore FGF23 in bone metabolism illustrated by the long-term disease process of our clinical case we would like to introduce these parameters to a broader public.

methodsWe performed a literature search via PubMed and Google Scholar with the relevant key words and summarized the diagnostic and therapeutic information. The studies evaluated were mainly case reports. We present a case report of a 70-year-old patient with TIO and a myopericytoma and retrospectively analyzed the clinical case. The follow-up was 6 months.

resultsOur literature search found one case of TIO and evidence of FGF23 among 124 cases of myopericytomas in total. Over 300 cases of TIO are reported. In our case, we retrospectively found an FGF23-secreting myopericytoma in the phosphaturic mesenchymal tumors (PMT) group to be the cause of pseudarthrosis on the right humerus shaft and increasing disablement in a patient with osteomalacia. After surgical resection the patient was mobile again, and the osteologic parameters, especially phosphate, normalized from 0.21 to 1.52 mmol/l.

conclusionLow phosphate levels are the decisive indication of TIO in our case. Therefore, we should always think of phosphate level control when dealing with osteomalacia. A hypophosphatemia and hyperphosphaturia should be recognized in time and be diagnostically verified. The additional FGF23 test (c-terminal and intact FGF23) should be considered.
