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
backgroundThis study aims to explore the mechanism of drug resistance in multiple myeloma (MM).
methodsIn this study, the possible mechanism of chemotherapeutic tolerance was preliminarily explored from two aspects: (I) the changes in cell morphology, cell cycle, cell apoptosis, stem cell markers and the signaling transduction pathway after the irradiation of RPMI-8226 cells; (II) the mechanism of enhancing chemotherapeutic sensitivity through the PI3K/AKT/mTOR signaling pathway.
resultsThe results showed that the cell morphology and cell cycle of RPMI-8226 had been significantly changed after receiving a radiation dose of 6 Gy in the logarithmic growth phase, the sensitivity of cells to bortezomib had been decreased, the level of stem cell markers had been upregulated, and the PI3K/AKT/mTOR signaling pathway had been activated. However, blocking the PI3K/AKT/mTOR signaling pathway caused the expression of the stem cell markers of RPMI-8226 cells. In addition, the sensitivity of cells to bortezomib had been increased.
conclusionsBlocking the PI3K/AKT/mTOR might decrease the RPMI-8226 cells which survived the radiotherapy and increase the sensitivity of cells to bortezomib.
