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

backgroundIt is increasingly recognized that non-opioid analgesia is an important analgesia in the perioperative period. Specifically, NSAIDs (nonsteroidal anti-inflammatory drugs) have been touted as an adjunct, or even replacement, for opioids. However, uptake of NSAIDs has been slow due to concern for side effects, including bleeding. We sought to understand the risk of bleeding caused by NSAIDs in the perioperative period. STUDY

designA physician-librarian team performed a search of electronic databases (MEDLINE, EMBASE), using search terms covering the targeted intervention (use of NSAIDs) and outcomes of interest (surgical complications, bleeding), limited to English language articles of any date. We performed a systematic review and meta-analysis of the data.

resultsA total of 2,521 articles were screened, and 229 were selected on the basis of title and abstract for detailed assessment. Including reference searching, 74 manuscripts met inclusion criteria spanning years 1987-2019. These studies included 151,031 patients. Studies included 12 types of NSAIDs, the most common being ketorolac, diclofenac, and ibuprofen, over a wide-range of procedures, from otorhinolaryngology (ENT), breast, abdomen, plastics, and more. More than half were randomized control trials. The meta-analyses for hematoma, return to the operating room for bleeding, and blood transfusions showed no difference in risk in any of 3 categories studied between the NSAID vs non-NSAID groups (p = 0.49, p = 0.79, and p = 0.49, respectively). Quality scoring found a wide range of quality, with scores ranging from lowest quality of 12 to highest quality of 25, out of a total of 27 (average = 16).

conclusionsNSAIDs are unlikely to be the cause of postoperative bleeding complications. This literature covers a large number of patients and remains consistent across types of NSAIDs and operations.
