B vitamin status, dietary intake and length of stay in a sample of elderly rehabilitation patients.
Article in The journal of nutrition, health & aging, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 papers.
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
objectivesTo investigate the relationships between previous diet, biomarkers of selected B vitamins, nutritional status and length of stay.
designCross sectional study.
settingGeriatric rehabilitation patients, Sydney, Australia.
participantsFifty two consenting patients with normal serum creatinine levels and no dementia. MEASUREMENTS: Serum vitamin B12, plasma vitamin B6, serum and erythrocyte folate, homocysteine and methylmalonic acid (MMA) concentrations; dietary intake using a validated semi-quantitative food frequency questionnaire and nutritional assessment using the Mini Nutritional Assessment (MNA). Length of stay data were collected from medical records after discharge.
resultsThe age was 80 ± 8 year (mean ± SD), BMI 26.4 ± 6.8 kg/m2 and MNA score 22 ± 3 indicating some risk of malnutrition. Deficiencies of vitamins B6, B12 and folate were found in 30, 22 and 5 subjects respectively. Length of stay was positively correlated with age and MMA (Spearman's correlation 0.4, p<0.01 and 0.28, p<0.05 respectively) and negatively correlated with albumin, vitamin B6 and MNA score (Spearman's correlation -0.35, -0.33 and -0.29, p<0.05). After adjustment for age and sex, ln vitamin B6 and ln MMA concentrations were significant in predicting ln LOS (p=0.006 and p=0.014 respectively).
conclusionThe study indicates a high risk of vitamin B deficiencies in the elderly and suggests that deficiencies of vitamins B6 and B12 are associated with length of stay. This is concerning as B vitamin status is rarely fully assessed.
