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
Graphene-based THz absorbers have found widespread applications in cutting-edge technologies. Although this area has attracted significant research interest, the lack of an analytical model for accurately analyzing graphene-based THz absorbers remains a major challenge. In this work, an analytical model is introduced to address this gap. Based on this model, key design parameters are extracted and incorporated into a modified framework. Using the modified model, a systematic design procedure for a THz absorber with a graphene layer is proposed. Following this procedure, a THz absorber with array of one-layer graphene ribbons is designed by considering possible fabrication tolerances, and its performance-calculated using the analytical model-is compared with numerical results. The comparison confirms the accuracy of the analytical approach. The proposed absorber achieves more than 90% absorption over a broad frequency range from 0.65 to 1.44 THz (frequency bandwidth 76%). This THz absorber demonstrates strong potential for applications in sensing and communication technologies.
