1 · What the graph read from 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.

2 · The registry

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

objectiveIdiopathic pulmonary fibrosis (IPF) substantially impairs health-related quality of life (HRQoL). The IPF-specific St George's Respiratory Questionnaire (SGRQ-I) is not available in Turkish. This study aimed to translate, culturally adapt, and validate the SGRQ-I for Turkish-speaking patients with IPF. MATERIAL AND

methodsFollowing international guidelines, the SGRQ-I underwent forward translation, reconciliation, back translation, developer review, and cognitive debriefing. Adult patients with IPF were consecutively recruited. Validity was assessed against the Turkish SGRQ and by examining associations with forced vital capacity (FVC), diffusing capacity for carbon monoxide (DLCO), the six-minute walk test (6MWT), gender-age-physiology (GAP) stage, modified Medical Research Council (mMRC) grade, and long-term oxygen therapy (LTOT) status. Test-retest reliability was assessed over seven days in clinically stable patients.

resultsOne hundred eighty patients were included (mean age 66.3±10.0 years; 36% male). Agreement with the SGRQ was excellent for the activities, impact, and total scores [intraclass correlation coefficients (ICC) >0.90] and moderate for the symptoms score. The SGRQ-I total score was significantly correlated with FVC% (r = -0.476), DLCO% (r = -0.406), and 6MWT distance (r = -0.462, all

conclusionThe Turkish SGRQ-I is a valid and reliable instrument for assessing HRQoL in IPF, supporting its use in clinical practice and multinational research.
