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

The reversing effects of carvedilol and other beta-adrenoceptor antagonists on multidrug resistance (MDR) were assessed in HeLa cells and the MDR1-overexpressing derivative Hvr100-6 cells, established by stepwise increases of vinblastine concentration in the culture medium. The inhibitory effects on the transcellular transport and intracellular accumulation of [3H]vinblastine and [3H]daunorubicin were also assessed using LLC-GA5-COL150 cell monolayers, established by transfection of human MDR1 cDNA into porcine kidney epithelial LLC-PK1 cells. The cytotoxic effects of vinblastine, paclitaxel, doxorubicin and daunorubicin in Hvr100-6 were reversed 1.4- to 7.1-fold by carvedilol at the realistic clinical concentration of 1 microM, whereas other beta-adrenoceptor antagonists had weaker or no such effects. Transport experiments using LLC-GA5-COL150 cell monolayers demonstrated that this effect of carvedilol was due to the inhibition of MDR1-mediated transport of vinblastine, paclitaxel, doxorubicin and daunorubicin. These MDR1-mediated reversing effects of carvedilol were similar to those of 1 microM verapamil, suggesting that carvedilol could be a candidate modulator of MDR in clinical use. Since other beta-adrenoceptor antagonists had no inhibitory effect on transport, the effects of carvedilol were not related to beta-adrenoceptors and might have been due to antioxidant activity.
