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

Follicle-stimulating hormone (FSH)-producing pituitary neuroendocrine tumor is very rare and usually present with menstrual disorders, ovarian cysts, polycystic ovary morphology (PCOM), and so on. It is often confused with polycystic ovary syndrome (PCOS) and is difficult to diagnose. Missed or misdiagnosis may lead to unnecessary surgical injury or severe neurologic damage. We describe the case of a 37-year-old woman with persistent menstrual disturbances and ovarian cysts. Because of unceasing ovulation after usage of combined oral contraceptive (COC) she was suspected of having endogenous uncontrolled FSH and eventually a pituitary adenoma was found. In addition, we review the features of onset, diagnostic history, treatment, and prognosis of previous similar reports. We find the symptoms of FSH-secreting pituitary adenomas puzzling. Mild cases are easily overlooked, and severe cases are easily misdiagnosed as ovarian hyperstimulation syndrome and ovarian tumors and receive unnecessary pharmacological and surgical interventions. Attention to abnormal sex hormones is key to diagnosis, and prompt surgical tumor removal is important.
