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
objectiveAccurate assessment of inhaler adherence is essential for optimizing treatment outcomes in patients with chronic obstructive pulmonary disease (COPD). This study aimed to evaluate the validity and reliability of the Turkish version of the Test of Adherence to Inhalers (TAI) in a multicentre COPD cohort. MATERIAL AND
methodsA total of 277 patients were included. Sociodemographic characteristics and adherence status [assessed by the Turkish version of the Medication Adherence Report Scale-5 (MARS-5);
resultsThe mean age was 66.3±8.3 years, 81.9% of participants were male. Most patients (73.6%) used at least two inhaler devices, and 28.9% were classified as non-adherent according to İUBÖ. Based on TAI scores, 43.3% of patients had good adherence, 23.8% had intermediate adherence, and 32.9% had poor adherence. CFA supported the two-factor structure of the TAI (Tucker-Lewis Index: 0.965; Comparative Fit Index: 0.972; Root Mean Square Error of Approximation: 0.114). Criterion validity was demonstrated by good agreement between TAI and İUBÖ (kappa: 0.637,
conclusionThe Turkish version of the TAI is a valid and reliable tool for assessing inhaler adherence in patients with COPD and is suitable for both clinical practice and research settings in Türkiye.
