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 perception of quality of life (QOL) is a subjective concept; however, attempts have been made to discern the key points and to give a metric view of this concept. The World Health Organization Quality of Life Questionnaire-Older Adults (WHOQOL-OLD) module is an international and cross-cultural tool that quantifies the QOL in older adults.
objectivesThis study aimed to assess the psychometric properties of the Hindi version of the WHOQOL-OLD module by calculating its reliability and validity among the elderly residing in the Dehradun district of India. METHODOLOGY: This cross-sectional study was conducted among 440 elderlies from the rural and urban areas of Dehradun by using the Hindi version of the WHOQOL-OLD questionnaire. The mean and standard deviations were calculated for QOL scores. Reliability was checked by calculating Cronbach's alpha (α), and factor analysis was done for the validity of the questionnaire.
resultsMean (±SD) for total QOL score was 54.3 (±9.3). The death and dying facet had the maximum mean score, whereas the minimum mean score was calculated in the autonomy facet. Cronbach's alpha reliability coefficient for the overall QOL score was calculated as 0.86 which shows good internal consistency of the items in the questionnaire. To measure the construct validity, exploratory factor analysis (EFA) by principal components analysis (PCA) was performed on the 24 items of the WHOQOL-OLD module, and a six-factor model was identified. Satisfactory goodness-of-fit statistics were found on the confirmatory factor analysis (CFA).
conclusionQOL is a multidimensional concept. The Hindi version of the WHOQOL-OLD module is reliable and valid. QOL in the elderly population can be measured by using the WHOQOL-OLD module in India.
