Prevalence and risk factors of preoperative malnutrition risk in older patients and its impact on surgical outcomes: a retrospective observational study.
Observational study in Canadian journal of anaesthesia = Journal canadien d'anesthesie, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 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
purposeElderly patients are vulnerable to malnutrition and we have started systematic screening for preoperative malnutrition risk in our institution. This study aims to determine the prevalence and risk factors of preoperative malnutrition risk among elderly surgical patients, and its impact on surgical outcomes.
methodsIn this retrospective cohort study of patients ≥ 65 yr old undergoing elective surgery, we recorded demographics, medications, preoperative effort tolerance, Malnutrition Universal Screening Tool (MUST) score, American Society of Anesthesiologists physical status (ASA), Charlson Comorbidity Index (CCI), and Edmonton Frailty Score (EFS). Postoperative complications based on the Clavien-Dindo (CD) classification and hospital length of stay (LOS) were also recorded.
resultsOf the 1,033 patients studied, 123 (11.9%) were at risk of malnutrition (MUST ≥ 1), with 48 (4.6%) at high risk (MUST ≥ 2). Unadjusted predictors for high malnutrition risk included ASA ≥ III, higher EFS, higher CCI, polypharmacy (≥ ten medications), poor effort tolerance (metabolic equivalent of tasks < 3), malignancy, general surgery patients, and lower hemoglobin. These patients had higher odds of CD grade ≥ 1 complications compared with those without risk (adjusted odds ratio, 2.30; 95% confidence interval [CI], 1.11 to 4.78; P = 0.025) and 22% longer hospital LOS (adjusted incidence rate ratio,1.22; 95% CI, 1.00 to 1.49; P = 0.049) after multivariate adjustment for sex, severity of surgery, comorbidities, frailty, malignancy, and anemia.
conclusionPreoperative malnutrition risk is prevalent among the elderly. Patients at high malnutrition risk have increased risk of postoperative complications and longer hospital LOS. Patients with high comorbidity burden and frailty should be screened for malnutrition so that nutritional optimization can be sought.
