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

backgroundThe Composite Autonomic Symptom Score 31 (COMPASS-31) is a validated self-report questionnaire designed to assess autonomic symptoms across six domains. A Brazilian Portuguese version has not yet been formally validated.

methodsFollowing a standardized Mayo Clinic linguistic validation protocol, the COMPASS-31 was translated into Brazilian Portuguese. Twenty-one patients with disorders associated with autonomic symptoms and nine healthy controls completed both the English and Portuguese versions in randomized order, with a six-week interval between administrations. Reliability was assessed using kappa coefficients and Bland–Altman analysis. Validity was evaluated by comparing scores between patients and controls and by correlating the Portuguese and English versions.

resultsThe Brazilian Portuguese version of the COMPASS-31 demonstrated good test–retest reliability and a strong correlation with the original English version (r = 0.784, p < 0.0001). Patients exhibited significantly higher total scores than healthy controls. Bland–Altman analysis showed good agreement, with 93.4% of values falling within the limits of agreement.

conclusionsThe Brazilian Portuguese version of the COMPASS-31 is a valid and reliable instrument for assessing autonomic symptoms in both clinical and research settings.
