Complications and diagnostic accuracy of CT-guided 18G tru-cut versus end-cut percutaneous core needle biopsy of solitary solid lung nodules.

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
purposePercutaneous biopsy has demonstrated high accuracy in diagnosis of lung nodules, but the technique is not innocuous and a yield decrease in lesions smaller than 20 mm has been reported. We carried out a prospective study to evaluate and compare the complications and efficacy of percutaneous core needle biopsy (CNB) of solitary solid lung nodules, which were performed with two types of automatic guns.
methods330 consecutive CT-guided CNB were included. Tru-cut or end-cut 18G devices were used alternatively. Nodules were categorized by their size: ≤10 mm, 11-20 mm and >20 mm. Incidence of complications such as pneumothorax or hemoptysis and factors influencing them (nodule size and depth within lung parenchyma) were evaluated. Diagnostic accuracy of CNB achieved in the three groups of nodules regarding the two different needles were calculated and statistically evaluated and compared.
resultsWe performed 68 CNB in nodules ≤10 mm, 130 in 11-20 mm and 132 in >20 mm. Pneumothorax appeared in 24.2% of them, but only 5.7% required drainage. Hemoptysis was developed in 9.4% and abundant hemoptysis with hypoxemia was observed in only 4.2% of patients. Regarding appearance of complications between the two needle types, no significant differences were found. A higher risk of hemoptysis was observed in nodules ≤10 mm (OR = 3.87; 95% CI = 1.24-12.06, P = 0.019) and in those located deeper in pulmonary parenchyma (OR = 2.21; 95% CI = 1.04-4.69, P = 0.038). End-cut needles reached a diagnostic accuracy of 93.7%, 92.1% and 98.3%, in nodules sized ≤10 mm, 11-20 mm and >20 mm, respectively. Corresponding results for tru-cut were 84.7%, 88.5% and 92.1%. In spite of differences reaching up to 9% in smaller nodules, intra-group results were not significant.
conclusionBoth needles have similar complications rate. Despite not having observed statistically significant differences between the two types of needles, end-cut devices have demonstrated a higher diagnostic yield in the three groups of nodules and could be a more suitable option especially for CNB of nodules ≤10 mm.
