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

objectiveTo evaluate the measurement properties of the Brazilian version of the Copenhagen Neck Functional Disability Scale (CNFDS) in patients with chronic neck pain.

methodsOne hundred and five patients were included in the study. The structural validity of the CNFDS was assessed by exploratory and confirmatory factor analysis with the following fit indices: chi-square divided by degrees of freedom (chi-square/df), root mean square error of approximation (RMSEA), comparative fit index (CFI), and Tucker-Lewis index (TLI). To test the construct validity, the CNFDS score was correlated with the Numerical Pain Rating Scale, the Tampa Scale of Kinesiophobia, the Pain-Related Catastrophizing Thoughts Scale, and Neck Disability Index (NDI). A subsample of 43 patients filled the CNFDS at two different times, and test-retest reliability was measured using the intraclass correlation coefficient (ICC), standard error of measurement (SEM), and minimum detectable change (MDC). The internal consistency of the CNFDS was analyzed by Cronbach's alpha.

resultsCNFDS presented a unidimensional structure, with goodness of fit indices: chi-square/df = 1.37, CFI = 0.94, TLI = 0.93, RMSEA = 0.059. The CNFDS showed satisfactory results of reliability (ICC = 0.93) and internal consistency (Cronbach's alpha = 0.84). The SEM was 1.72 and the MDC was 4.76. The CNFDS showed a high correlation with the NDI (rho = 0.718) and a low correlation with the other instruments. There were no floor and ceiling effects.

conclusionThe Brazilian version of the CNFDS with a one-dimensional structure and 15 items has adequate measurement properties.
