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.
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
purposeTo perform a comprehensive psychometric analysis of the Boston Carpal Tunnel Syndrome Questionnaire (BCTQ) by means of factor and Rasch analyses in subjects with neurophysiologic confirmation of carpal tunnel syndrome (CTS). Relationship between clinical severity assessed with the log-linear version of the BCTQ and neurophysiologic severity assessed with nerve conduction studies was further examined.
methodsFive hundred and twenty-eight individuals completed the questionnaire. Confirmatory and exploratory factor analyses were used to determine the latent structure of the BCTQ. Through Rasch methodology, a log-linear version was proposed given the latent structure of the questionnaire. Linear relationship between the proposed questionnaire and neurophysiologic findings was established.
resultsThe BCTQ underlying structure comprises, at least, three factors that may be represented by Functionality, Paresthesia and Pain domains. Two log-linear subscales may be proposed: subscale 1 comprised of the Functionality factor and subscale 2 which incorporates the Paresthesia and Pain factors under a bifactor solution. Neurophysiologic and clinical severity classification system displays a very weak linear correlation.
conclusionA log-linear version of the BCTQ, useful as an outcome tool in clinical and trial settings, is proposed. Neurophysiological data lack the ability to resemble changes in clinical status of individuals with CTS.
