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

Paragangliomas (PGLs) are rare neural crest-derived tumors with highly variable morphology and clinical behavior. These tumors can present with cystic and necrotic alterations that may influence the clinical presentation of affected patients. However, prevalence and clinical significance of these pathological alterations remain poorly understood. In this retrospective study (2011-2021), 103 patients with confirmed PGLs were examined for cystic and necrotic alterations based on imaging and pathology reports as well as pathological re-evaluation. Cystic alterations, including microscopic, macroscopic, and pseudocystic alterations, were observed in 61.8% of PGLs. Regardless of their pathomorphological presentation, cystic alterations did not affect the clinical presentation of these patients. In contrast, necrotic alterations were identified in 3.9% of PGLs and were associated with a higher rate of metastasis (75% vs. 10%, p = 0.0124), larger tumor volume (53.6 cm
