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

purposeA high percentage of cancer patients use complementary and alternative medicine (CAM). The aim of our study was to learn more about the association of CAM usage, information needs, perceived impact of disease, locus of control and self-efficacy of cancer patients.

methodsWe asked patients attending a series of lectures on CAM using a standardized questionnaire which integrated questions on information needs, CAM and validated short questionnaires on self-efficacy, perception of the disease and locus of control of reinforcement.

resultsOne hundred and eighty-five patients answered the questionnaire, from whom 45 % used CAM. Sixty percentage disclosed using CAM to the general practitioner and 57 % to the oncologist. Physicians and nurses, print media and the Internet are the most important source of information on CAM (used by 20-25 % each). Impact on neither daily life, perceived personal control nor coherence was associated with CAM usage, disclosure to physicians or sources of information. There also was no association between CAM usage and self-efficacy. In contrast, there was a significant association between CAM user rate and a high external locus of control.

conclusionWhile CAM usage is agreed upon by many physicians due to the idea that it helps patients to become active and feel more in control of the disease, our data are in favor of the contrary. A strong perception of external locus of control seems to be a driver of CAM usage. Physicians should be aware of this association when counseling on CAM.
