Correlations between plasma endothelin-1 levels and breakthrough pain in patients with cancer.

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
Endothelin-1 (ET-1) may be involved in driving pain in patients with advanced cancer. However, a few studies focus on the role of ET-1 in breakthrough pain (BP). The aim of this pivotal study was to explore the correlation between the plasma (ET-1) level and BP intensity. A total of 40 patients were enrolled in the study, and they were divided into two groups: BP group and non-BP group. Moreover, 20 healthy adults were used as the normal control group. Pain intensity was measured using visual analog scale (VAS) scores of 1-10. Plasma ET-1 levels were detected by an ET radioimmunoassay kit. Subsequently, the correlation of ET-1 level with the VAS score and cancer types was analyzed by Pearson's correlation coefficient. The plasma ET-1 level in the BP group (35.31±8.02 pg/mL) was higher than that in the non-BP group (29.51±6.78 pg/mL) and the normal control group (24.77±10.10 pg/mL, P<0.05). In addition, the VAS score in the BP group (7.45±0.82) was higher than that in the non-BP group (2.80±1.23, P<0.05). The plasma ET-1 level was positively correlated with the VAS score of the BP group (Pearson's r=0.42). There was no significant correlation between the plasma ET-1 level and VAS score of the non-BP group (Pearson's r=-0.22) or/and cancer types (P>0.05). The elevated plasma ET-1 levels were positively related to BP, and targeting ET-1 may provide a novel pain-reducing therapeutic treatment in BP.
