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

backgroundAdrenal schwannomas (AS) are extremely rare neoplasms. This study shares our experience regarding the diagnosis and operative management of AS.

methodsClinical details, radiologic, laboratory, and pathologic findings as well as follow-up data were analysed retrospectively for 13 AS patients who accepted surgery at a tertiary referral hospital in China between 1 January 1996, and 31 December 2017.

resultsThe mean age of the patients at diagnosis was 44.7 ± 13.7 years (range 19-62 years; male: female ratio, 1:1.16), of whom seven patients had unilateral AS on the right side, and the remaining six on the left side. None of the cases were hormonally active. None of the 13 cases were diagnosed as AS by CT imaging before the operation. Among the patients, ten were asymptomatic. The mean preoperative size was 7.1 ± 3.2 cm (range 1.6-12.6 cm). All patients underwent surgery, with open adrenalectomy in five patients and laparoscopy in eight patients. The mean tumor size on pathologic examination was 6.8 ± 3.0 cm (range 3.0-11.7 cm). The surgical specimens were confirmed by pathological examination. During a median follow-up of 60.8 ± 17.7 months, no patients showed recurrence or metastasis.

conclusionThe preoperative diagnosis of AS remains difficult despite the advances in imaging examinations. After complete resection, the prognosis of AS is excellent.
