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
Background: In pediatric patients, nasal polyps primarily manifest as anthrochoanal polyps (ACP) or chronic rhinosinusitis with nasal polyps (CRSwNP). This study compares the histopathological differences between pediatric ACP and CRSwNP, analyzes pathological indicators associated with postoperative recurrence and provides evidence for subtype-specific diagnosis and treatment. Materials and methods: This retrospective study analyzed demographic factors, comorbidities and a structured histopathologic report of six variables from 172 pediatric patients (86 with ACP and 86 with CRSwNP) who underwent functional endoscopic sinus surgery. Differences between recurrent and non-recurrent presentations were further examined. Results: Mean age in the ACP group was significantly lower than the CRSwNP group ( Conclusion: Pediatric ACP is characterized by prominent subepithelial edema. A lack of collagen deposition indicates a higher risk of recurrence. CRSwNP features severe inflammation, which positively correlates with recurrence.
