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
backgroundThe Bronchiectasis Health Questionnaire (BHQ), a 10-question instrument designed to assess quality of life and disease-specific issues, was developed in 11 languages, including English. The present study aims to translate the original version of the BHQ into Turkish using a standardised methodology and to evaluate the validity and reliability of the Turkish version of the BHQ.
methodsThis cross-sectional study was conducted at Giresun Training and Research Hospital between August 2024 and January 2025, with ethical approval (decision number 03.07.2024/03) and informed consent from all participants. A total of 132 clinically stable participants with bronchiectasis were enrolled. The study was performed in two stages: (1) cross-cultural adaptation of the original Bronchiectasis Health Questionnaire (BHQ) into Turkish (T-BHQ) according to established guidelines, and (2) psychometric validation of the T-BHQ. Alongside the T-BHQ, data on socio-demographics, clinical characteristics, mMRC dyspnea score, pulmonary function tests, Bronchiectasis Severity Index (BSI), SF-12 quality of life questionnaire, and exacerbation history were collected. Reliability was assessed using Cronbach's alpha and test-retest analysis, while construct validity was evaluated through exploratory and confirmatory factor analyses, convergent validity with clinical measures, and Bland-Altman analysis.
resultsThe validity and reliability of the T-BHQ were evaluated in present study involving a total of 134 participants with bronchiectasis, and a Cronbach's alpha of 0.729 was obtained. In the exploratory factorial analysis, factorial loadings of > 0.40 were determined for all items and were evaluated as appropriate. Utilising the Bland-Altman analysis to assess the test's repeatability, (mean difference: 0,059, β = 0.03, p:0.840). The convergent validity of the T-BHQ with mMRC was strong (r = - 0.648, p:< 0.001), with BSI were moderate (r: -0,437, p:<0,001), while concurrent validity with SF-12 subtypes mainly were at a moderate level (Physical role functioning: r = - 0.661 p:<0.001, other subtypes at a moderate level).
conclusionsThe T-BHQ has been demonstrated to possess both reliability and validity in evaluating the disease-related quality of life and health status of participants with bronchiectasis in Turkey.
