1 · What the graph read from it

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.

2 · The registry

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

Bitter taste receptors (TAS2Rs) are increasingly recognised as extraoral chemosensors that modulate diverse biological processes, including cancer cell behaviour and drug responsiveness. Many TAS2R ligands correspond to therapeutic compounds; however, their contribution to the response of brain tumours to chemotherapy remains unexplored. Here, we investigated whether the bitter taste signalling pathway is modulated by temozolomide (TMZ), the standard chemotherapeutic agent for glioblastoma, with an impact on treatment efficacy in glioblastoma cells. We show that TMZ elicits intracellular Ca
