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
The SH3PXD2A-HTRA1 fusion gene has recently been identified in a subset of schwannomas, but its frequency and clinical significance remain unclear. This study aimed to investigate the prevalence and clinical relevance of this fusion gene in intracranial schwannomas, stratified by cranial nerve of origin. We retrospectively investigated the fusion gene in 237 intracranial schwannomas. Fusion detection was performed using reverse transcription polymerase chain reaction and confirmed by Sanger sequencing. Somatic NF2 status was evaluated using whole-genome sequencing or Merlin immunohistochemistry in fusion gene-positive cases. Clinical characteristics and postoperative tumor recurrence were compared between fusion gene-positive and fusion gene-negative tumors, and subgroup analyses were performed by cranial nerve of origin. The fusion gene was detected in 30 tumors (12.7%), with the highest frequency observed in trigeminal schwannomas (25.9%). Tumors classified as recurrent at baseline (odds ratio [OR], 3.74; P = 0.012), trigeminal nerve origin (OR, 2.88; P = 0.042), and intratumoral hemorrhage (OR, 18.61; P = 0.028) were significantly associated with fusion gene-positive tumors. In the trigeminal schwannomas, fusion gene-positive cases were significantly younger (P = 0.029). In the vestibular schwannomas, recurrence status was found to be independently associated with positive fusion gene status (OR, 4.53; P = 0.010). Furthermore, even after gross or nearly total resection, fusion gene-positive vestibular schwannomas exhibited a significantly higher incidence of recurrence after surgery (P = 0.046). Only 33% of fusion gene-positive tumors indicated somatic NF2 alteration. The SH3PXD2A-HTRA1 fusion gene may define a molecular subset of intracranial schwannomas with distinctive anatomical distribution and biological aggressiveness. It may contribute to tumorigenesis through an alternative pathway independent of NF2. Our findings provide a basis for future clinical investigations.
