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

backgroundThis study aimed to investigate the effects of ultrasound-guided quadratus lumborum block (QLB) on perioperative multimodal analgesia and postoperative outcomes in patients undergoing radical prostatectomy.

methodsA total of 80 patients undergoing radical prostatectomy were randomly divided into two groups: general anaesthesia with QLB (QLB group; n = 40) and general anaesthesia with sham QLB (normal saline [NS] group; n = 40). QLB or sham QLB was performed before the induction of anaesthesia. Sufentanil was intravenously administered for postoperative analgesia. The primary outcome was the pain score (measured using a numerical rating scale [NRS]) at different time points within 48 h postoperatively. Secondary outcomes included the cumulative dose of sufentanil within 48 h postoperatively, subjective comfort, grip strength, first time of exhaustion, first fluid intake time, time to get out of bed, length of postoperative hospital stay and overall satisfaction. The SPSS software, version 17.0, was used for all statistical analyses.

resultsPostoperative NRS at rest was significantly lower at 2 h (1.7 ± 1.1 versus 3.0 ± 2.1), 4 h (1.8 ± 1.2 versus 4.1 ± 2.3), 6 h (1.9 ± 2 versus 4.4 ± 2) and 12 h (3.5 ± 2.3 versus 5 ± 3.3) and was also lower when coughing at 2 h (2.3 ± 1.1 versus 4 ± 2.1), 4 h (2.3 ± 1. 1 versus 4.3 ± 2) and 6 h (2.4 ± 1.1 versus 5.9 ± 2.3) in the QLB than that in the NS group. The cumulative dose of sufentanil was significantly lower in the QLB than that in the NS group at 4 h, 6 h, 12 h, 24 h and 48 h. The nausea score was significantly lower in the QLB group at 24 h postoperatively, and the first time of exhaustion and time to get out of bed were significantly shorter (P < 0.05). The overall satisfaction score was significantly higher in the QLB than in the NS group (4 ± 0.7 versus 2.6 ± 0.9).

conclusionUltrasound-guided bilateral QLB can provide effective postoperative analgesia for patients undergoing radical prostatectomy, reduce the need for sufentanil, facilitate comfort and improve postoperative outcomes. QLB can be a good component of multimodal analgesia.
