Risk factors for postoperative pneumonia in patients undergoing hip fracture surgery: a systematic review and meta-analysis.
Synthesis in BMC musculoskeletal disorders, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 23 papers, 1 of them a synthesis 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
backgroundPostoperative pneumonia (POP) is a devastating complication that can frequently occur after hip fracture surgery. This study aimed to quantitatively and comprehensively summarize the risk factors for POP following hip fracture surgery.
methodsPubMed, Embase, and Cochrane Library were systematically searched for studies assessing risk factors for POP following hip fracture surgery. The pooled odds ratio (OR) and standardized mean difference (SMD) between patients with and without POP were calculated. Evidence was assessed using the Newcastle-Ottawa scale.
resultsTen studies including 37,130 patients with hip fractures were selected. POP occurred in 1768 cases with an accumulated incidence of 7.8% (95% confidence interval [CI]: 0.061-0.094). Advanced age (SMD: 0.50, 95% CI: 0.10-0.90), male sex (OR: 1.50, 95% CI: 1.12-2.01), American Society of Anesthesiologists physical status scale ≥3 (OR: 3.17, 95% CI: 1.25-8.05), chronic obstructive pulmonary disease (OR: 2.05, 95% CI: 1.43-2.94), coronary heart disease (OR: 1.82, 95% CI: 1.27-2.60), arrhythmia (OR: 1.49, 95% CI: 1.04-2.15), congestive heart failure (OR: 1.41, 95% CI: 1.14-1.75), chronic kidney disease (OR: 2.09, 95% CI: 1.28-3.41), and cerebrovascular accident (OR: 2.14, 95% CI: 1.60-2.85) were risk factors for POP. Hemoglobin (SMD: -0.14, 95% CI: - 0.25 to - 0.03), albumin (SMD: -0.97, 95% CI: - 1.54--0.41), blood urea nitrogen (SMD: 0.20, 95% CI: 0.03-0.37), alanine aminotransferase (SMD: 0.27, 95% CI: 0.10-0.44), arterial oxygen pressure (SMD: -0.49, 95% CI: - 0.71--0.27), time from injury to surgery (SMD: 0.13, 95% CI: 0.08-0.17), and surgery within 48 h (OR: 3.74, 95% CI: 2.40-5.85) were associated with the development of POP.
conclusionPatients with the aforementioned risk factors should be identified preoperatively, and related prophylaxis strategies should be implemented to prevent POP following hip fracture surgery.
