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

introductionPostoperative delirium (POD) is the most common acute fluctuating mental state change after hip fractures in older adults. Postoperative pain is a Grade A risk factor for POD and is closely related to the prognosis of patients undergoing hip fracture surgery. The fascia iliac block has a definite analgesic effect and few side effects, and several studies have reported that it reduces the occurrence of POD in patients undergoing general anaesthesia for hip fracture surgery. Liposomal bupivacaine is a local anaesthetic with a long half-life that significantly reduces the use of opioids and is conducive to patient prognosis and recovery. However, whether regional nerve block analgesia can decrease the occurrence of POD in elderly patients undergoing hip fracture surgery has not been reported. METHODS AND ANALYSIS: This is a single-blinded, randomised, parallel-controlled prospective clinical study. Participants will be randomly assigned preoperatively to either the liposomal bupivacaine (ie, Exparel) or ropivacaine groups by block randomisation. Then, the occurrence of POD (primary outcome) and postoperative pain (secondary outcome) will be evaluated. ETHICS AND DISSEMINATION: This research protocol complies with the Standard Protocol Items: Recommendations for Interventional Trials (SPIRIT) 2013 guidelines and is approved by the Ethics Committee of Shanghai General Hospital (ID 2023-437). The original data are expected to be released in July 2029 on the ResMan original data-sharing platform (IPD-sharing platform) of the China Clinical Trial Registry, which can be viewed on the following website: http://www.medresman.org.cn. PROSPERO REGISTRATION NUMBER: ChiCTR2300074022.
