Methodological quality and reporting of ethical requirements in phase III cancer trials.
Article in Journal of medical ethics, 2005. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled 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.
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
backgroundThe approval of a research ethics committee (REC) and obtaining informed consent from patients (ICP) could be considered the main issues in the ethics of research with human beings. The aim of this study was to assess both methodological quality and ethical quality, and also to assess the relationship between these two qualities in randomised phase III cancer trials.
methodMethodological quality (Jadad score) and ethical quality (Berdeu score) were assessed for all randomised controlled trials (RCTs) published in 10 international journals between 1999 and 2001 (n = 231).
resultsThe mean Jadad score was 9.86 +/- 1.117. The methodological quality was poor in 75 RCTs (Jadad score <9). The mean Berdeu score was 0.42 +/- 0.133. The mean ethical quality score for poor methodological quality RCTs (n = 75) was 0.39 +/- 0.133; it was 0.43 +/- 0.133 for good (n = 156) methodological quality RCTs (p = 0.07). There was improvement in ethical quality according to the year of commencement of the trials (p < 0.001). There was no correlation between methodological quality and the number of participating patients (R2 = 0.003, p = 0.78), between ethical quality and the number of participating patients (R2 = 0.003, p = 0.76 ), or between ethical quality and methodological quality (R2 = 0.012, p = 0.1). ICP and REC approval were not obtained for 21 and 77 trials respectively.
conclusionThe association between methodological quality and the reporting of ethical requirements probably reflects the respect shown for patients during the whole research process. These results suggest that closer attention to the conduct of clinical research, as well as the reporting of its ethical aspects, is needed.
