Endobronchial ultrasound-guided transbronchial fine needle aspiration: Determinants of adequacy.
Article in Turk gogus kalp damar cerrahisi dergisi, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundThis study aims to evaluate the factors influencing the adequacy of endobronchial ultrasound-guided transbronchial fine needle aspiration specimens.
methodsA retrospective analysis of 1,700 endobronchial ultrasound-guided transbronchial fine needle aspiration samples obtained from 822 patients (500 males, 322 females; mean age 56±13 years; range 16 to 83 years) was performed between March 2011 and March 2014 at our center. Variables potentially associated with sampling adequacy, such as all cytological materials and procedure notes (lymph node and/or lesion size, localization, needle pass number, and slide number) were examined.
resultsThe overall specimen adequacy was 79.8%. The specimen adequacy was associated with needle pass number (p≤0.001). Adequacy rate was 66.9% for one needle pass and 85.8% for three needle passes. According to the sampling regions, adequacy rates showed a difference [69.2%-85.8%; (p≤0.005)]. In the multivariate logistic regression analysis of subcarinal (7) lymph node station, patient age (odds ratio, 0.983; 95% confidence interval, 0.966-1.000; p=0.049) and number of slides (odds ratio, 1.240; 95% confidence interval, 1.062-1.448; p=0.006) were independent determining factors of specimen adequacy. While independent determinants of specimen adequacy for the right paratracheal (4R) region were lymph node size (odds ratio, 1.486; 95% confidence interval, 0.973-2.268; p=0.067) and number of slides (odds ratio, 1.418; 95% confidence interval, 1.146-1.756; p=0.001), they were lymph node size (odds ratio, 1.594; 95% confidence interval, 0.960-2.645; p=0.071) and number of needle passes (odds ratio, 2.277; 95% confidence interval, 1.360-3.811; p=0.002) for the right interlobar (11R) region. Independent determinant of specimen adequacy for the left paratracheal (4L) lymph node station was the number of needle passes (odds ratio, 1.656; 95% confidence interval, 0.955-2.869; p=0.072).
conclusionDuring endobronchial ultrasound-guided transbronchial fine needle aspirations, particularly when rapid on site evaluation cannot be applied, consideration of factors affecting adequacy according to lymph node localizations may increase the chance for obtaining materials with suitable quality for cytologic evaluation.
