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
purposeThe aim of this study was to determine the frequency of opioid-induced neurotoxicity (OIN) in cancer patients receiving oral controlled-release oxycodone and to define risk factors for OIN.
methodsThis was a single-center, retrospective study of hospitalized adult cancer patients receiving oral controlled-release oxycodone between April 1, 2013, and April, 30, 2020. The onset of OIN within 30 days after oxycodone initiation in the study patients was investigated. OIN was defined as any of the following: delirium, hallucinations (visual or auditory), seizure, myoclonus, hyperesthesia, and excessive somnolence. Multivariate logistic regression analysis was performed to identify risk factors for OIN in patients receiving oxycodone.
resultsIn total, 520 patients were included in this study. The number of patients with OIN was 65 (12.5%). The median time until onset of OIN after oxycodone initiation was 7.5 days. Multivariate logistic regression analysis revealed that age ≥ 65 years (OR = 2.74, 95% CI [1.30-5.78], p = 0.008), total bilirubin ≥ 1.3 mg/dL (OR = 4.85, 95% CI [2.13-11.0], p < 0.001), and concomitant use of pregabalin or mirogabalin (OR = 3.11, 95% CI [1.47-6.61], p = 0.003) were significant independent risk factors for OIN.
conclusionAge ≥ 65 years, liver dysfunction, and concomitant use of pregabalin or mirogabalin were independent risk factors for OIN in patients receiving oxycodone. Patients with these risk factors who are receiving oxycodone should be monitored for OIN, especially early in the administration of oxycodone.
