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
purposeThis study aimed to evaluate the clinical characteristics associated with post-operative recurrence in patients with sinonasal inverted papilloma (IP), focusing on the prognostic factors influencing recurrence-free survival (RFS).
methodsWe retrospectively reviewed clinical records from patients who underwent surgery for IP between January 1, 2007, and August 31, 2023. RFS was analyzed using Kaplan-Meier method and Cox proportional hazard regression analyses to identify the prognostic factors for recurrence. Variables, including age, sex, symptoms, timing of diagnosis, radiological findings, Krouse staging, previous surgery history, surgical method, and tumor origin site, were analyzed.
resultsAmong the 315 patients with IP, 48 experienced recurrences. The survival analysis revealed 1-, 3-, and 5-year RFS rates of 88.88%, 82.84%, and 69.47%, respectively, and indicated that headache, diagnosis during or following surgery, high Krouse staging, intracranial extension, and frontal sinus origin reduce median RFS or the 5-year RFS rate. Multivariate Cox regression showed that headache, diagnoses made during or after surgery, intracranial extension, and frontal sinus origin significantly increased recurrence risk.
conclusionsIf IP is suspected, a biopsy should be performed, and an appropriate surgical approach should be planned. To select the appropriate surgical method, determining the tumor origin site using radiological imaging is crucial, particularly in cases involving the frontal sinus or intracranial extension. Additionally, vigilant monitoring is essential for identifying recurrences early in patients with significant risk factors.
