1 · What the graph read from 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.

2 · The registry

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

purposeWisQoL (Wisconsin Stone Quality of Life questionnaire) is a disease specific, health related quality of life measure designed for patients who form kidney stones. The goal of this study was to develop and validate a German version of WisQoL.

methodsThe German version of the WisQoL was developed following a standardized multistep process. Patients were recruited prior to stone treatment, and completed the questionnaire as well as the SF-36v2 (36-Item Short Form Health Survey). This was repeated 1, 3, and 6 months after stone surgery. Scores of the 28 questionnaire items were summarized into sum scores for four domains and a total score. The psychometric properties of the questionnaire were statistically analyzed.

resultsThe German WisQoL demonstrated excellent internal consistency (Cronbach's α > 0.90 for all domains at all visits). All inter-domain associations were positive. The test-retest reliability for patients with unchanged self-reported health state was considered satisfactory (Spearman's rho for total score 0.70 [95% CI 0.55 to - 0.80]). The German WisQoL demonstrated good convergent validity with the validated SF-36v2 (correlation between corresponding items 0.44 to 0.64). All domain scores showed significant sensitivity to change induced by stone treatment (p ≤ 0.05). Total WisQoL scores generally improved during the first 3 months following stone treatment, and remained stable thereafter.

conclusionThe German WisQoL proved to be a reliable and robust instrument to evaluate health related quality of life measures of kidney stone patients in the clinical setting. It is expected to be of use for further research in patients with kidney stones.
