Mortality after emergency versus elective groin hernia repair: a systematic review and meta-analysis.
Synthesis in Surgical endoscopy, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 21 papers, 2 of them syntheses that pooled 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.
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
backgroundEmergency groin hernia repair is associated with increased mortality risk, but the actual risk is unknown. Therefore, this review aimed to investigate 30- and 90-day postoperative mortality in adult patients who had undergone emergency or elective groin hernia repair.
methodsThis review was reported following PRISMA 2020 guidelines, and a protocol (CRD42021244412) was registered to PROSPERO. A systematic search was conducted in PubMed, EMBASE, and Cochrane CENTRAL in April 2021. Studies were included if they reported 30- or 90-day mortality following an emergency or elective groin hernia repair. Meta-analyses were conducted when possible, and subgroup analyses were made for bowel resection, sex, and hernia type. According to the study design, the risk of bias was assessed using either the Newcastle-Ottawa Scale or Cochrane Risk of Bias tool.
resultsThirty-seven studies with 30,740 patients receiving emergency repair and 457,253 receiving elective repair were included. The 30-day mortality ranged from 0-11.8% to 0-1.7% following emergency and elective repair, respectively. The risk of 30-day mortality following emergency repair was estimated to be 26-fold higher than after elective repair (RR = 26.0, 95% CI 21.6-31.4, I
conclusionThe overall mortality after emergency groin hernia repair is 26-fold higher than after elective repair, but the increased risk is attributable mostly to female and femoral hernias.
