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
Introduction: Solid pancreatic lesions (SPL)s can be due to various etiologies, and their management depends on the histologic diagnosis. Aim: The aim of this study was to document the etiology, morphology, and utility of macroscopic on-site evaluation (MOSE) in predicting good yield of endoscopic ultrasound (EUS)-guided biopsy. Material and methods: All patients with SPLs referred for EUS-guided biopsy were included in the study. Etiology, morphology and results of EUS-guided biopsy were recorded. Rapid on-site evaluation (ROSE) was not available; therefore, MOSE was performed by an endoscopist. Macroscopically, MOSE was considered satisfactory if at least 1 tissue core at least 1 inch long was secured. Histopathologically, a biopsy specimen was considered to have a good yield if it was sufficient to establish a diagnosis. Factors predicting good yield of biopsy (GYB) were identified. Results: Of the total 176 patients included in the study, 111 (63.1%) were male (mean age 53.8 (±12.6) years; range: 14-80 years). Good yield biopsies (GYB) numbered 144 (81.8%); among them, 97 (67.4%) were neoplastic and 47 (32.6%) non-neoplastic SPLs. The commonest neoplastic SPLs were pancreatic ductal adenocarcinoma (PDA) (76; 78.3%), neuroendocrine tumors (NETs) (13; 13.4%), metastasis (5; 5.1%), and others (3; 3.1%), while the commonest non-neoplastic SPLs were mass-forming chronic pancreatitis (MFCP) (33; 70.2%), autoimmune pancreatitis (AIP) (5; 10.6%), and tuberculosis (2; 4.3%). PDAs were more common in older patients (65/76; 85.5%) and in the head region of the pancreas (47; 61.8%), while NETs were more common in younger patients 7/13 (53.8%) and in the body of the pancreas 5/13 (38.5%). Factors predicting GYB were SPL size > 15 mm ( Conclusions: The commonest neoplastic SPLs are PDA and NET, and the commonest non-neoplastic SPLs are MFCP and AIP. PDAs have a predilection for the head region and older age, while NETs have a predilection for younger patients and the body of the pancreas. A good biopsy yield is likely with use of FNB needles and satisfactory MOSE.
