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
backgroundThe human peripheral nervous system embodies anatomical, physiologic, and diagnostic perplexities that remain unexplained. Yet in the course of human history, there are no mechanisms, such as computed tomography (CT) or radiography, by which to image the peripheral nervous system in vivo using a contrast agent that is identified by ionizing radiation, which would aid in surgical navigation, diagnostic radiology, and basic science thereof.
methodsA novel class of contrast was created by linking iodine to lidocaine. The radiodensity of 0.5% experimental contrast molecule was compared with a control of 1% lidocaine by placing 1.5-mL aliquots of each liquid into centrifuge tubes and performing micro-computed tomography (micro-CT) synchronously under identical settings. Physiologic binding to the sciatic nerve was evaluated by injecting 10 mg of the experimental contrast and 10 mg of the control into the contralateral sciatic nerve, and documenting loss of hindlimb function and recovery. In vivo visualization of the sciatic nerve was evaluated by injecting 10 mg of experimental contrast or control into either sciatic nerve and imaging the hindlimbs under identical conditions using micro-CT.
resultsThe mean Hounsfield unit of the contrast was 56.09 compared with -0.48 for control (116-fold increase,
conclusionIodinated lidocaine offers a viable mechanism for in vivo peripheral nerve imaging using CT; however, it requires modification to improve in vivo radiodensity.
