Visual Analogue Score for Urinary Symptoms-VASUS, validation of a visual scale for lower urinary tract symptoms (LUTS) in an African country.
Article in World journal of urology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeValidate a visual scale to assess LUTS, especially in developing countries, as an alternative to IPSS. VASUS consist of five questions, where Q1 and Q2 assess urinary stream quality, Q3 nocturia, Q4 incomplete emptying and Q5 QoL.
methodsBetween 2014 and 2017, we carried out a study in the male population over 30 years from São Tomé and Príncipe, a Portuguese speaking African Country. A stratified sample (age and district) of subjects completed IPSS, VASUS and a free flowmetry.
resultsWe obtained 812 valid responses (average age: 50.72, range: 30-95 years old). In the comparison between IPSS and VASUS, we found positive correlations, with p value < 0.0001, for all variables analyzed and negative correlation for all urodynamic variables. Upon verifying the association of VASUS with IPSS, namely when comparing questions with similar objectives such as nocturia (VASUS-Q3 and IPSS-Q7), the stream quality (VASUS-Q1 and Q2 and IPSS-Q5) or the quality of life (VASUS-Q5 and IPSS-Q8), strong positive correlations were found.
conclusionVASUS is a visual alternative to IPSS allowing evaluation of LUTS and having correlation with IPSS and flowmetry. Its use in developing countries with low levels of literacy will be an asset. The authors believe that widespread use of a scale such as VASUS in urology consultations is warranted, to increase daily practice objectification of LUTS.
