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

aimThe aim of this study was to evaluate the validity and reliability of the Turkish version of the European Organization for Research and Treatment of Cancer (EORTC) QLQ-ELD14 in older patients with cancer.

methodsOne hundred thirteen older patients with cancer were included in the study. The validity and reliability of the EORTC QLQ-ELD14 were evaluated via exploratory and confirmatory factor analyses, correlation analyses with the EORTC QLQ-C30, known-group comparisons, Cronbach's alpha, test-retest and the intraclass correlation coefficient. Known-group comparisons were evaluated in patient groups divided according to cancer stage, Karnofsky performance status and Charlson Comorbidity Index.

resultsFactor analysis results demonstrated that the Turkish EORTC QLQ-ELD14, with its seven-factor structure, is a sufficient measurement instrument. Moderate to high correlations were observed between the EORTC QLQ-ELD14 and the QLQ-C30 (r = -0.40 to -0.83; p < 0.05). The clinical validity of the EORTC QLQ-ELD14 has been demonstrated by its ability to discriminate between different clinical profiles. Cronbach's α coefficient was determined to be 0.719. The intraclass correlation coefficients of all subscales were above 0.80. Excellent agreement was observed in test-retest reliability.

conclusionThe Turkish version of EORTC QLQ-ELD14 is valid and reliable and is suitable for use by researchers and clinicians.
