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

backgroundThe pericapsular nerve group (PENG) block, quadratus lumborum block (QLB), and intra-articular (IA) local anesthetic injection have been shown to provide effective analgesia in total hip arthroplasty (THA). This randomized study aimed to compare the analgesic efficacy, motor protection, and quality of recovery associated with the PENG block, QLB, and IA injection.

methodsEighty-nine patients who underwent a unilateral primary THA under spinal anesthesia were randomly assigned to the PENG (n=30), QLB (n=30), or IA (n=29) group. The primary outcome was the numerical rating scale (NRS) score over the first 48 h postoperatively. The secondary outcomes were postoperative opioid consumption, quadriceps and adductor muscle strength, and quality of recovery (QoR-40).

resultsThe dynamic (with movement) NRS scores at 3 and 6 h postoperatively were significantly lower in the PENG and QLB groups compared to the IA group (P = 0.002 and P < 0.001, respectively). The time to first opioid analgesia requirement was longer in the PENG and QLB groups than in the IA group (P = 0.009 and P = 0.016, respectively). A provided better preservation was found in the the PENG group than in the QLB group in terms of quadriceps muscle strength at 3 h postoperatively (P = 0.007) and time to mobilization (P = 0.003). No significant differences in the QoR-40 scores were seen.

conclusionsThe PENG and QLB groups showed similar analgesic effects and both showed more effective analgesia 6 h postoperatively than the IA group. All the groups showed similar postoperative quality of recovery.
