An empirical comparison of the WHOQOL-BREF and the SGRQ among patients with COPD.
Article in Quality of life research : an international journal of quality of life aspects of treatment, care and rehabilitation, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT07469111 (Effects Of Low-Load Blood Flow Restriction Training Of The Upper Extremity In Patients With Chronic Obstructive Pulmonary Disease), which is not on this map.

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.

Abstract
aimsTo compare the psychometric properties of the World Health Organization Quality of Life-BREF (WHOQOL-BREF) instrument and the St. George's Respiratory Questionnaire (SGRQ), and to examine the association between pulmonary function and domains and items of these questionnaires in patients with chronic obstructive pulmonary disease (COPD).
methodsThe WHOQOL-BREF and the SGRQ were administered to 211 patients. The reliability and validity of, and correlations among, the domain scores were examined. Multiple regression analyses were performed to identify which items were independently associated with subjects' lung functions.
resultsBoth questionnaires showed good internal consistency (alpha > 0.8), except the SGRQ symptoms domain (alpha = 0.66), minimal ceiling and floor effects, and good item convergent and item discriminant validity. There were moderate correlations between physical domain of the WHOQOL-BREF and activity, impacts and total domains of the SGRQ, and between psychological domain of the WHOQOL-BREF and impacts and total domains of the SGRQ. Eighteen items were significantly associated with lung function, particularly those items relating to mobility/walking and activities of daily living (ADL).
conclusionBoth the WHOQOL-BREF and the SGRQ showed comparable reliability and validity. Items related to mobility/walking and ADL may be useful in clinical screening for lung function impairment.
