Efficacy and Validity of Image-Guided Percutaneous Fine Needle Aspiration and Core Biopsy of Liver Pathologies: Saga of Focal Hepatic Lesions from the Nodule to the Needle to the Slide.
Article in Journal of cytology. 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
contextRadiology and pathology are pivotal tools in the investigational artillery for management of wide spectrum of hepatic lesions and early detection is of a paramount importance.
aimsThe study aimed at analyzing the efficacy, comparative yield and validity of image-guided aspiration cytology (FNA)/core biopsy (CB) in focal hepatic lesions. SETTINGS AND
designA retrospective hospital-based study was conducted in departments of Pathology and Radiology and Imaging of a tertiary care center. MATERIALS AND
methodsCases of focal hepatic lesions that underwent percutaneous image guided-FNA reported (2011-2018) were analyzed. Cytological-histopathological correlation was performed where available. FNA diagnoses were divided into four categories-positive for malignancy (group 1), atypical (group 2), negative for malignancy (group 3), and non-diagnostic (group 4). STATISTICAL ANALYSIS USED: Categorical data was depicted in the form of frequencies and proportions. Validity of percutaneous image-guided FNA diagnosis was collated with the final diagnosis and results were analyzed.
resultsA total of 338 FNA of focal hepatic lesions were reported in which 217 (68.2%) cases in group 1; 21 (6.2%) in group 2; 58 (17.2%) in group 3 and 42 (12.4%) in group 4. CB correlation was available in 123 cases. Based on clinical, radiological and pathological findings, conclusive final diagnoses were obtained and the cases were regrouped [malignant cases-245, benign lesions-57 and uncertain lesions-36]. Metastasis was the most common malignancy (175/245; 71.4%). Sensitivity, specificity, and overall diagnostic accuracy of FNA to categorize the lesion as benign or malignant were 96.94%, 100% and 97.51%, respectively. However, the cytology-histopathology correlation revealed discordance of subtyping the lesion in 20% of cases and sensitivity and specificity reduced to 80% and 50% respectively in rendering the specific diagnosis.
conclusionsPercutaneous image-guided FNA is a sensitive and specific tool with high diagnostic accuracy in evaluating focal hepatic lesions. The study highlights the pre-eminence of interventional radiology and cytology in the care of patients with liver lesions.
