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
BACKGROUND It is important to have a psychometrically sound instrument assessing inhaler adherence of patients with chronic obstructive pulmonary disease (COPD). The present cross-cultural study aimed to validate the Chinese translation of the 10-item Test of Adherence to Inhalers (TAI) among 235 Taiwanese patients with COPD. MATERIAL AND METHODS The TAI was translated into Chinese and validated for Taiwanese patients with COPD. Eight experts evaluated the Chinese TAI, and their scores were used to examine content validity. Then, a total of 235 COPD patients (93.6% male, n=220; mean age=72.18 years, SD=10.19) were recruited using convenience sampling. A research assistant and a respiratory therapist conducted interviews to help patients complete the TAI and other related measures. Exploratory factor analysis, internal consistency, and relationship between TAI-defined adherence groups and the statement "Don't take medicine when there are no symptoms" were used to validate the Chinese TAI. RESULTS The content validity and internal consistency of the Chinese TAI were good (content validity index=0.975 for relevance, and 0.988 for clarity; alpha=0.82). The exploratory factor analysis suggested a single-factor structure. Moreover, the TAI-defined adherence groups had significantly different responses to the statement "Don't take medicine when there are no symptoms". CONCLUSIONS The Chinese TAI assessing inhaler adherence among Taiwanese patients with COPD effectively helps patients with COPD to identify their inhaler adherence. Researchers and healthcare providers can use the translated TAI to monitor adherence to inhaler for patients with COPD in Taiwan.
