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
Aim of the study: Our hypothesis is that nirmatrelvir can penetrate the blood‒brain barrier and reach effective concentrations in the brain. Furthermore, herbal formulations can help maintain nirmatrelvir levels in the body, suggesting potential interactions between these medications. Materials and methods: To investigate this hypothesis, an animal model combining multisite microdialysis, ultrahigh-performance liquid chromatography and tandem mass spectrometry (UHPLC-MS/MS) methods was developed to monitor nirmatrelvir levels in the blood and brain of rats. Results: The pharmacokinetic results showed that the area under the curve (AUC) of nirmatrelvir in the blood and brain was 798.3 ± 58.56 and 187.2 ± 23.46 min μg/mL, respectively, after the administration of nirmatrelvir alone (15 mg/kg, iv). When the Conclusions: These results provide constructive preclinical information that the concentrations of nirmatrelvir in the blood and brain were greater than the effective concentration (EC
