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
This study aims to investigate the clinical characteristics of programmed cell death protein-1 (PD-1) or programmed cell death ligand-1 (PD-L1) inhibitors-induced pituitary injury (pituitary-irAE) by comparing with other pituitary diseases. We retrospectively reviewed clinical records of patients who were admitted for pituitary-irAE, idiopathic isolated ACTH deficiency (IIAD), and lymphocytic hypophysitis (LYH) from January 2015 to June 2024. Among 3689 patients treated with PD-1/PD-L1 inhibitors, 0.596% patients developed pituitary-irAE. The mean age of onset was 59.41 ± 10.69 years, with 13 patients (59.09%) being male. The median duration from symptom onset to confirmed diagnosis was 5.50 (2.00, 9.25) months. The clinical symptoms were similar between pituitary-irAE and IIAD, which mainly manifested as fatigue and appetite loss. Polydipsia/polyuria and amenorrhea/menstrual disorders were mainly found in patients with LYH. Central adrenal insufficiency was observed in all patients with pituitary-irAE, with cortisol concentrations typically falling below the detectable limit. Pituitary MRI appeared normal in 52.63% patients with pituitary-irAE. Furthermore, some patients with pituitary-irAE exhibited partial or complete functional recovery of the pituitary gland after hormone replacement therapy. The clinical manifestations observed in patients with pituitary-irAE are analogous to those seen in individuals with IIAD, yet they differ from the presentations of LYH.
