1 · What the graph read from it

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.

2 · The registry

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

Background: Effective perioperative pain management for patients undergoing hand surgery is critical because of the risk of opioid misuse. Complementary approaches, including auriculotherapy (AT), for perioperative pain management have gained increasing attention. This study was designed to assess the analgesic properties of AT in patients undergoing endoscopic carpal tunnel surgery (CTR). Materials and methods: This retrospective study analyzed medical records of patients who underwent unilateral ambulatory CTR performed by a single surgeon under a regional block plus sedation, with or without the use of AT using a cryogenic approach. All procedures were performed between 1 October 2016 and 30 May 2017. A total of 38 consecutive patients were included in the analysis. At discharge, patients received a standard analgesic prescription for 3 days and were asked to record pain scores, using a verbal scale (0-10), and analgesic consumption on postoperative days (POD) 1, 2, and 3. The primary end points were overall consumption-expressed as the area under the curve (AUC) for oral morphine equivalent (OME) in mg-and pain scores between POD1 and POD3. Secondary end points included pain and opioid and non-opioid analgesic consumption. Data are presented as median (interquartile range) (25-75 percentile); Results: A total of 38 consecutive patients were included in the analysis. There were 19 patients in the AT group (16 women and three men), with a mean age 54 ± 7.9 years, and 19 patients in the control group (15 women and four men), with a mean age of 57 ± 12.8 years. The use of cryo-AT was associated with a 44% reduction in OME consumption (0.0 [0.0; 10.0] OME mg in the AT group vs. 10 mg [0.0; 30.0] OME mg in the control group; Discussion: Our study suggests that cryogenic AT is an effective complementary alternative to opioids to control postoperative pain following CTR. Further investigations are required to confirm these findings.
