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
objectiveThe objective of this study was to validate the Continence Specific Pediatric Quality Of Life Measurement Tool (PinQ) questionnaire into Portuguese and compare its effectiveness with the Dysfunctional Voiding Symptom Score (DVSS) questionnaire in assessing the quality of life in children with lower urinary tract dysfunction (LUTD).
methodsThe PinQ questionnaire was translated into Portuguese using Beaton's methodology, which consists of six phases: (1) Initial Translation; (2) Synthesis; (3) Back Translation; (4) Final Version; (5) Prefinal Version Testing; and (6) Presentation. Each patient received 15 sessions, consisting of one evaluation and application of questionnaires and 14 treatment sessions (sacral neurostimulation + behavioral therapy + central stabilization, diaphragm and transverse abdominal muscle recruitment and pelvic floor muscle activation), with the questionnaire reapplied at the end. The scores obtained from both questionnaires before and after treatment were used to compare treatment efficacy and validate the PinQ questionnaire.
resultsA total of 300 sessions were conducted with 20 patients, each receiving 15 weekly sessions, with an average age of 8.95 years. The analysis of the PinQ questionnaire showed an improvement of symptoms (Score before: mean 37.7; deviation±15.9 and Score after: mean 26.8; deviation±12.9 with p=0.0051), as well as the DVVSS questionnaire (Score before: mean 11, deviation 3.4 and Score after: mean 7.7, deviation 4 with p=0.0055), with a significant improvement in the quality of life of children as assessed by both questionnaires.
conclusionsThis study confirmed the effectiveness of a Portuguese-language tool that evaluates the real impact of quality of life in children and adolescents with LUTD.
