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) is well known as an important technique for diagnosis and staging of lung cancer. But a standard protocol to deal with patients who have a negative pathology result still needs to be defined. Herein, we describe the subsequent procedures of these patients in a single center.
methodsA total of 1,412 patients with clinical suspected lung cancer and mediastinal metastasis who underwent EBUS-TBNA were collected between September 2010 and December 2016. Among them, 51 patients with nonspecific pathology result were included and retrospectively analyzed.
resultsThe 51 patients were stratified into five groups by clinical characterize and follow-up procedures: (1) Diagnosed by other bronchoscopy procedures group (9 cases). Abnormalities of tracheobronchial tree were found during visual examination in the majority of patients (8 cases). Biopsy, endobronchial brushing, bronchoalveolar lavage, and transbronchial lung biopsy (TBLB) were used to get a specific diagnosis. (2) EBUS-TBNA re-biopsy group (11 cases). Patients in this group had normal mucosal appearance and airway lumen. Re-biopsy were performed on patients in this group. (3) Surgery group (6 cases). Patients underwent surgery after negative result of EBUS-TBNA. Five of them were confirmed with non-nodal metastasis after surgery. (4) Underwent other pathology diagnosis group (15 cases). patients in this group had other metastasis sites besides midiastinal lymph node. Computed tomography (CT)-guided fine-needle aspiration and lymph node biopsy were performed. (5) Follow-up group (10 cases). None invasive procedure was used in this group. The median follow up time was 38 months. One patient was diagnosed lymphoma during the follow up.
conclusionsDiagnostic procedures should be chosen based on the clinical character in EBUS-TBNA negative patients with suspected lung cancer. Long time follow-up is very important in patients whose diagnosis is apparently unknown.
