Acquired thyroid-stimulating hormone, luteinizing hormone, and follicle-stimulating hormone deficiencies with circulating anti-glycoprotein hormones alpha chain-positive cell antibodies.

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.
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
backgroundA patient with systemic lupus erythematosus (SLE) suffered from acquired thyroid-stimulating hormone (TSH), luteinizing hormone (LH), and follicle-stimulating hormone (FSH) deficiencies. MRI findings revealed a slight atrophy of the pituitary gland. Further, the serum concentration of the covalent alpha subunit (glycoprotein hormones alpha chain [CGA]) in TSH-, LH-, and FSH-positive cells was below the detectable range. Because SLE is an autoimmune disorder, autoimmunity against the pituitary gland was suspected as the cause of pituitary deficiency. METHODS AND
resultsImmunofluorescence analysis showed that the patient's immunoglobulin G recognized CGA-positive cells in the pituitary gland; therefore, autoimmunity against CGA-positive cells may have caused TSH, LH, and FSH deficiencies in this patient. Moreover, cell-specific autoimmunity impairs pituitary hormone levels. Further research is required to clarify whether acquired TSH, LH, and FSH deficiencies are common in patients with SLE or other autoimmune diseases.
conclusionOur findings highlight a unique case of acquired TSH, LH, and FSH deficiencies caused by circulating anti-CGA-positive cell antibodies, introducing a novel clinical concept of acquired hypopituitarism.
