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
objectiveTo distinguish squamous cell carcinoma in inverted papilloma (IP-SCC) from IP, the utility of CT scoring system was investigated.
methodsWe extracted cases histopathologically diagnosed with IP and IP-SCC of the sinonasal cavity from June 2004 to May 2021. Preoperative unenhanced CT images were used to evaluate the presence or absence of bone destruction and erosion: Score 1 = positive for bone destruction and/or erosion; Score 0 = negative for bone destruction and erosion. The CT scores in 10 sites of the sinonasal cavity and their adjacent areas were calculated.
resultsFifty-six cases of IP and 20 cases of IP-SCC were enrolled in this study. Bone destruction and/or erosion was more frequently observed in IP-SCC than in IP at the sites of the skull base (p = 0.0001), orbital wall (p < 0.0001), maxillary sinus (p < 0.0001), nasal septum (p < 0.0001), inferior nasal concha (p = 0.0046), ethmoid sinus (p < 0.0001), pterygoid process (p = 0.0031), and frontal sinus (p = 0.0009). The total CT scores at the 10 sites for diagnosing IP-SCC had sensitivity and specificity of 70% and 87.5% (AUC: 0.810, p < 0.001); furthermore, those at the eight sites excluding fontanelle and middle nasal concha improved sensitivity and specificity of 75% and 83.9% (optimal threshold of 2, AUC: 0.862, p < 0.001).
conclusionThe CT scoring system evaluating bone destruction and erosion could accurately differentiate IP-SCC from IP.
