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

BACKGROUND AND

objectivesThere is no data regarding validity and reliability of the Greek version of Neurogenic Bladder Symptom Score (NBSS) questionnaire. In this study we investigated these parameters using a sample of Greek patients with multiple sclerosis (MS). MATERIALS AND

methodsPatients with different types and severity of multiple sclerosis were recruited from a single center in Greece prospectively. All patients completed the MusiQoL and NBSS questionnaires at baseline and 20 days later, without receiving any new treatment. Construct validity, internal consistency and test-retest reliability were tested. Internal consistency was investigated using Cronbach's alpha coefficient, while test-retest reliability using Intraclass Correlation Coefficient (ICC). Construct validity was assessed by comparing NBSS quality of life question 24 with MusiQoL questionnaire.

resultsA total of 91 patients were evaluated. The dimensions of NBSS exhibited high internal consistency, both for overall questionnaire score (Cronbach's alpha coefficient of 0.91) and for every subdomain separately (Cronbach's alpha coefficient of 0.95 for incontinence, 0.88 for storage symptoms and 0.74 for consequences). Test-retest reliability was satisfactory both for overall score [ICC of 0.85, (0.35-0.94), p < 0.001] and for every subdomain separately (ICC of 0.90 for incontinence, 0.83 for storage symptoms and 0.90 for consequences). Pearson's correlation coefficient of question number 24 of the NBSS questionnaire regarding quality of life with the MusiQoL questionnaire revealed a moderate correlation [r = 0.64, (0.48-0.80), p < 0.0001].

conclusionsThe Greek version of NBSS appears to be a valid and reliable instrument for assessing neurogenic bladder symptoms in Greek population suffering from multiple sclerosis.
