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

objectiveWe hypothesized that fibromyalgia (FM) patients would report lower levels of psychological control mechanisms and that higher levels of control would moderate key symptoms associated with FM, such as pain, fatigue, perceived stress, and mood disturbance.

methodsNinety-eight women with FM diagnosed according to American College of Rheumatology criteria and 35 matched pain-free women were identified. Applied questionnaires included the Fibromyalgia Impact Questionnaire, Profile of Mood States, Perceived Control of Internal States Scale, Perceived Stress Scale, and Mastery Scale. Differences were sought using t-tests, one-way analysis of variance, bivariate correlations, and multiple regression analysis.

resultsComparison between FM patients and healthy individuals found significant differences in control (Perceived Control of Internal States Scale and Mastery Scale), pain, perceived stress, fatigue, confusion, and mood disturbance (all P < 0.001). There were significant associations found between both high and low levels of control on stress, mood, pain, and fatigue (P < 0.001-0.05). Strong negative correlations were present between internal control and perceived stress (P < 0.0005).

conclusionFM patients use significantly different control styles compared with healthy individuals. Levels and type of psychological control buffer mood, stress, fatigue, and pain in FM. Control appears to be an important "up-stream" process in FM mechanisms and is amenable to intervention.
