Evaluation of postoperative pain by PainVision® PS-2100, a quantitative analyzer for perception and pain in pulmonary resection: a prospective pilot study.

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
purposePain intensity is typically assessed using qualitative scales, including the numerical rating scale (NRS), which has limitations in quantifying pain intensity. PainVision® PS-2100 (Nipro Corporation, Osaka, Japan) was developed to quantify pain as pain degree (PD); however, its ability to assess acute postoperative pain remains unclear. This prospective single-center pilot study aimed to evaluate the performance of PainVision® by comparing PD with NRS scores after lung resection surgery.
methodsFifty patients who underwent lobectomy or segmentectomy for lung tumors were enrolled. PD and NRS scores were measured twice daily, at rest and during mobilization, on postoperative days (PODs) 1, 2, 5, and 7. The correlation coefficient between PD and NRS scores on POD 1 was the primary endpoint. Secondary endpoints included the correlation coefficients on PODs 2, 5, and 7; the overall correlation coefficient across all measured data; and a comparison of postoperative trends in PD and NRS scores.
resultsOn POD 1, statistically significant weak-to-moderate positive correlations were observed between PD and NRS scores (r = 0.363-0.634, p < 0.05). Similar results were observed on PODs 2, 5, and 7 in most measurement conditions (r = 0.274-0.664). A statistically significant moderate correlation was observed across all measurements (n = 736; r = 0.575, p < 0.001). PD and NRS scores showed similar trends: values on POD 2 were comparable to POD 1, whereas PODs 5 and 7 were significantly lower.
conclusionPainVision® may be a feasible tool for quantifying acute postoperative pain following lung resection.
