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
introductionTransversus abdominis plane (TAP) blocks are commonly used for postoperative analgesia after various abdominal surgeries. There are several different approaches for performing TAP blocks, mainly including posterior, lateral and subcostal approaches. An increasing number of randomised controlled trials (RCTs) have compared the analgesic effects of different TAP block approaches, but the results have not been consistent. This protocol aims to determine the optimal approach of ultrasound-guided TAP blocks for postoperative analgesia after abdominal surgery. METHODS AND ANALYSIS: Four databases, including Web of Science, PubMed, EMBASE and the Cochrane Library will be systematically searched to identify RCTs that compared the analgesic effects of different ultrasound-guided TAP block approaches. The search interval will range from the inception of the databases to 30 July 2024. The postoperative opioid consumption over 24 hours will be defined as the primary outcome. The secondary outcomes will include the analgesia duration, postoperative pain scores at rest and during movement at different timepoints and the incidence of adverse effects. All the statistical analyses will be conducted using RevMan V.5.4. The quality of evidence will be evaluated by the Grading of Recommendations Assessment, Development and Evaluation approach. ETHICS AND DISSEMINATION: Ethical approval will not be needed. The results will be submitted to one peer-reviewed journal when completed. PROSPERO REGISTRATION NUMBER: CRD42024510141.
