The Patient and Observer Scar Assessment Scale: Translation for portuguese language, cultural adaptation, and validation.
Observational study in International wound journal, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 21 papers, 2 of them syntheses that pooled 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.
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
Evaluating scars is fundamental to analyse the outcome of treatments that include surgical intervention. Scales facilitate this type of assessment, but most of these measuring instruments are in different languages. The Patient and Observer Scar Assessment Scale (POSAS) is one of the most robust instruments available in the literature for the evaluation of scars, although there is no validated version in Brazilian Portuguese. The aims of this study were to culturally translate and validate POSAS for the Portuguese language of Brazil and to test its reproducibility, face validity, content, and construct. Following the methodology proposed by Beaton DE, Bombardier C, Guillemin F, Ferraz, MB, Spine 2000, 25, 3186, the questionnaire was translated and adapted to the Brazilian culture. The reproducibility, face, content, and construct validity were then analysed. In all, the scale was applied to 35 patients with postoperative scars (patient version) and 35 hand surgery specialists (version for the observer). The internal consistency was tested by Cronbach's alpha, and construct validation was performed by correlating the translated instrument with the Brazilian Portuguese translation of the Vancouver Scar Scale (VSS). The cultural adaptation of POSAS Escola Paulista de Medicina/Universidade Federal de São Paulo (EPM/UNIFESP) was confirmed. Both subscales showed strong internal consistency (Cronbach's α = 0.77-0.93), demonstrating reliability. The reproducibility was excellent, and the adapted scale demonstrated significant intra- and inter-observer reproducibility (r > 0.9) (P < 0.05). The validity of the construct was significant and showed good sensitivity between POSAS EMP/UNIFESP and the VSS. This study confirmed that POSAS EPM/UNIFESP can be used to evaluate patients with surgical scars in the Brazilian population. It has proven to be useful for clinical and research purposes, lending itself to capturing medical opinions and those of the patients themselves.
