AdultCarbQuiz for the Portuguese population with type 1 diabetes mellitus: translation, cultural adaptation and validation of its metabolic impact.

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
aimsIn type 1 diabetes mellitus (T1DM), functional insulin therapy, based on carbohydrate (CH) counting and individualized insulin-to-carbohydrate ratio, is essential to achieve an adequate metabolic control. However, to date, few tools have been validated to assess patients' knowledge about CH counting, with the AdultCarbQuiz questionnaire having proved to be a reliable method in an American cohort. The aim of this study was to translate, culturally adapt and validate the AdultCarbQuiz questionnaire for the Portuguese population.
methodsThis was a cross-sectional study of patients with T1DM on functional insulin therapy through continuous subcutaneous insulin infusion (CSII). Prior to its application, the AdultCarbQuiz questionnaire was translated and culturally adapted to the Portuguese context. Statistical analyses include descriptive, correlation and intern consistency analysis using IBM® SPSS® Statistics, version 27.
resultOne hundred patients were included, 58% of female sex, with a mean age of 31.09 ± 10.77 years. Mean disease duration was 15.04 ± 9.23 years, and mean CSII usage time was 4.02 ± 3.90 years. The average value of glycated haemoglobin (HbA1c), time in range (TIR), time above range (TAR) and time below range was, respectively, 7.32 ± 0.87, 59.75 ± 14.13, 34.38 ± 15.40 and 5.75 ± 6.58%. The average score of the questionnaire was 30.86 points ± 3.58 points, considered high. The Kuder-Richardson 20 coefficient value was 0.63 for the total score, with a Spearman-Brown value for the half-split of 0.63. Individuals with lower HbA1c values scored significantly higher on knowledge about hypoglycaemia prevention and correction (r = - 0.269, p = 0.007) and on the total questionnaire score (r = - 0.205, p = 0.041). A higher TIR and a lower TAR were also associated with a higher total score (r = 0.274, p = 0.007 and r = - 0.274, p = 0.007, respectively).
conclusionsIn this study, the AdultCarbQuiz questionnaire, translated and culturally adapted to the Portuguese context, proved to be a useful tool in assessing knowledge about CH counting in patients with T1DM, allowing to optimize, individually, the therapeutic strategy in consultation.
