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

backgroundTransversus abdominis plane (TAP) block can provide effective analgesia for abdominal surgery. However, many randomized controlled trials (RCTs) have shown controversial results in hysterectomy. We conducted a meta-analysis of RCTs to investigate the effectiveness of TAP block after hysterectomy.

methodsStudies were gathered from PubMed, MEDLINE, EMBASE, Cochrane Library, Web of Science, and ClinicalTrials.gov databases up to March 2018. RCTs involving TAP blocks in women undergoing hysterectomy were selected. The primary outcome of mean 24 hours morphine consumption and other outcomes, such as time to first request for analgesic, rest, and pain scores on movement at different times, and rates of nausea and vomiting, were compared between TAP block and no or sham block groups.

resultsA total of 841 participants were included in the 13 selected RCTs. Compared with no or sham blocks, TAP block reduced mean 24-hour morphine consumption in abdominal hysterectomy (AH) (weighted mean difference [WMD] -10.77 mg,

conclusionTAP block is an effective analgesic for AH. TAP block can reduce postoperative morphine consumption in AH and pain scores at rest and on movement for AH without increasing side effects. However, TAP block has limited analgesic effects for women undergoing LH/RH, as it does not reduce postoperative morphine consumption and pain scores at rest and on movement.
