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
backgroundEndobronchial ultrasound guided transbronchial needle aspiration (EBUS-TBNA) allows precise real-time sampling of intrathoracic lesions and is a minimally invasive, safe, and cost effective technique with high diagnostic yield. The aim of the current study is to evaluate utility of EBUS-TBNA cytology with cellblocks (CBs) in the diagnosis and subtyping of the intrathoracic lesions. MATERIALS AND
methodsIt was a prospective study conducted from October 2015 to October 2017. We received 233 cases of intrathoracic lesions for EBUS-TBNA, of which CB was made in 217 cases. A flexible endobronchial ultrasound scope was used to sample the lesions.
resultsThere were 89 females and 128 males amongst the total 217 patients (age range: 14-85 years, mean age: 48.35 years). The smears from EBUS-TBNA contained adequate material in 137/144 [95.1%] non-neoplastic cases and 34/36 [94.4%] of the neoplastic cases, whereas the CBs provided adequate material in 94/144 [65.3%] non-neoplastic cases and 37/40 [92.5%] neoplastic cases. The CB helped subtyping the malignancy in 19 cases and of these immunohistochemistry (IHC) was done on the CB in 15 cases. The biopsy was non-diagnostic in 17/36 cases of granulomatous pathology and 4/18 neoplastic cases diagnosed with EBUS-TBNA.3.
conclusionsEBUS-TBNA provides rapid diagnosis through cytology and the material recovered in the same setting for the CB preparation can be used for immunohistochemical analysis and it may at times provide the diagnosis in cases where the smears are non-diagnostic.
