Appropriate amounts proportions of lidocaine gel, indigo carmine and lipiodol mixture for preoperative marking in video-assisted thoracic surgery.

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
Preoperative marking is necessary in thoracoscopic wedge resections of lung nodules expected to be invisible or nonpalpable during surgery. Recently, lidocaine gel was added to a dye solution containing indigo carmine and lipiodol to promote micelle formation, but the optimal mixing ratio was not determined. Thus, an in vitro experiment was performed to identify the optimal mixing ratio of lidocaine gel, indigo carmine and lipiodol. To fixed volumes of indigo carmine and lipiodol of 0.5 ml each, 0.1, 0.2, 0.3, 0.4 and 0.5 ml of lidocaine gel was added. Changes were examined every 2 h. No changes were seen in the mixtures containing 0.1 and 0.2 ml of lidocaine gel, whereas those with 0.3, 0.4 and 0.5 ml had clearly separated after 2 h. Our findings suggest that the ideal proportion of indigo carmine, lipiodol and lidocaine gel for use in preoperative marking is 5:5:2.
