Early mortality after hip fracture surgery in COVID-19 patients: A systematic review and meta-analysis.
Review in Journal of orthopaedics. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 38 papers, 5 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
objectiveThe aim of this systematic review and meta-analysis was to assess the risk of early mortality in hip fracture patients with COVID-19 infection who undergo surgical intervention. DATA SOURCES: MEDLINE (PubMed) and CINAHL (Cumulative Index to Nursing and Allied Health Literature) databases. STUDY SELECTION: Studies were included in the systematic review if they reported postoperative mortality in patients with COVID-19 infection who underwent operative intervention for hip fracture. From this selection of studies, only investigations that reported postoperative mortality in a COVID-positive and a non-COVID group were included in the meta-analysis. DATA EXTRACTION: Data regarding patient demographics, age, and sex were recorded. Additional data that was extracted included study location, data collection period, length of follow-up, COVID testing methodology, COVID testing results, and number of patients who underwent operative versus nonoperative management. The primary outcome of interest was postoperative mortality. DATA SYNTHESIS: Random effects meta-analyses were performed to assess the pooled relative risk of postoperative mortality according to COVID status. Odds ratios and 95% confidence intervals (CI) were calculated.
conclusionsThe overall pooled mortality rate in the early postoperative period for hip fracture patients with concomitant COVID-19 infection was 32.6%. The relative risk for postoperative mortality in COVID-positive patients compared to non-COVID patients was 5.66 (95% CI 4.01-7.98; p < 0.001). The currently available literature demonstrates that COVID-19 infection represents a substantial risk factor for early postoperative mortality in the already susceptible hip fracture population. Further investigations will be needed to assess longer-term morbidity and mortality in this patient population. LEVEL OF EVIDENCE: Therapeutic Level IV.
