Comparison of intra-articular steroid injection and pericapsular nerve group block for pain control and functional outcomes in patients undergoing manipulation under anaesthesia for frozen shoulder - A randomised controlled trial.

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
Background and Aims: Manipulation under anaesthesia (MUA) for frozen shoulder is usually done under intra-articular steroid injection along with local anaesthetic agents. The pericapsular nerve group (PENG) block is also found to be effective for MUA. This study aimed to compare the efficacy of the PENG block with that of intra-articular steroid injections in patients with frozen shoulder. Methods: This randomised controlled trial was conducted on 130 patients aged 18-75 years with stage 2 or stage 3 frozen shoulder scheduled for manipulation under anaesthesia. The participants were randomly assigned into two groups: Group S (intra-articular steroid injection) and Group P (PENG block). Group S received ultrasound-guided intra-articular injection of 40 mg triamcinolone with 2 mL of 2% lignocaine and 2 mL of 0.5% bupivacaine. Group P received ultrasound-guided PENG block using 10 mL of 0.5% bupivacaine and 10 mL of 2% lignocaine. Numerical pain rating scale (NPRS) scores for pain were recorded at 15 min; 30 min; and 1, 6, 12, and 24 hours. Range of Motion (ROM) and Shoulder Pain and Disability Index (SPADI) were also assessed. Data were analysed using Statistical Package for Social Sciences 19.0, and Results: NPRS pain scores were significantly lower in the PENG group across all time points ( Conclusion: PENG block is effective in providing pain relief and improving shoulder function following MUA in patients with frozen shoulder.
