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
Collision tumors are exceptionally rare neoplasms characterized by simultaneous presence of two histologically distinct primary brain tumors in the same anatomic location. Their composition can pose a significant therapeutic challenge. Herein, we present a case of a successfully resected pineal region collision tumor composed of a pineocytoma and a pilocytic astrocytoma (PA). A 19-year-old female was admitted with obstructive hydrocephalus due to a pineal gland cyst and underwent surgical excision. Histopathological analysis confirmed a collision tumor comprising pineocytoma and PA. Collision tumors composed of both pineocytoma and PA are extremely rare, with limited cases reported. Their histological architecture presents a diagnostic challenge, requiring meticulous evaluation even by experienced neuropathologists. Given the rarity of such cases, increased awareness of these tumors will facilitate the development of standardized diagnostic criteria and treatment protocols. Multidisciplinary collaboration is essential for optimizing therapeutic strategies tailored to the specific histological composition of collision tumors.
