Development and Initial Validation of the Novel Scale for Assessing Quality of Life of Prostate Cancer Patients Receiving Androgen Deprivation Therapy.
Article in Chinese medical journal, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundThere has been no a specific scale to measure quality of life (QOL) for prostate cancer patients receiving androgen deprivation therapy (ADT) to date. This study aimed to develop and initially validate the scale to evaluate QOL for prostate cancer patients receiving ADT.
methodsThe scale was developed following international recommendations. Moreover, the items were all generated through literature review and referenced questionnaires. After being reviewed by expert panelists, the revised scale was formed and then completed by a convenience sample of 200 prostate cancer patients from our hospital. Explore factor analysis (EFA) was applied to test the construct validity, then split-half reliability, Cronbach's alpha, and test-retest reliability were applied to assess the reliability and stability of the scale.
resultsThe revised scale contained 22 items and a total of 200 participants had completed the scale. One hundred participants were randomly selected from the total 200 participants to perform EFA with varimax rotation on the revised scale, and "hot flashes" item was deleted for low factor loading. We selected only 3 items from each factor, then, the final scale was formed with 18-items. We selected another 100 participants to perform the EFA again on the final scale. It was demonstrated that the structure with 6 factors explained 72.5% of total variance and factor loading value was above 0.40 in all items of the factors. Moreover, the split-half reliability coefficient, Cronbach's alpha, and test-retest reliability coefficient were calculated to be 0.74, 0.63, and 0.89, respectively, exhibiting good reliability on the whole.
conclusionsThe scale was identified to be a valid and reliable instrument to measure QOL for prostate cancer patients receiving ADT. Moreover, further research is needed to overcome the potential drawbacks.
