Peak Expiratory Flow as an Index of Frailty Syndrome in Older Adults: A Cross-Sectional Study.
Article in The journal of nutrition, health & aging, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06974006 (Integrated Monitoring for Independent Living in Rural Settings), which is not on this map. Cited by 12 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.

Abstract
objectivesto compare the obtained and predicted peak expiratory flow (PEF) values between frail, pre-frail, and non-frail older adults; verify the association between PEF and FS; and establish cut-off points for PEF as determinants of frailty syndrome (FS).
designCross-sectional study. LOCATION: Macapá, Amapá, Brazil.
participantsCommunity-based study community-dwelling older people.
methodsPEF was evaluated using a peak-flow meter and FS was evaluated using Fried's frailty phenotype. The statistical analyses performed included a multinomial logistic regression model and Receiver Operating Characteristic (ROC) curves to establish cut-off points for discriminating FS.
results409 older adults with a mean age of 70.09±7.22 years were evaluated; of these, 58.7% were pre-frail, and 12.7% were frail. PEF was lower in frail than in pre-frail participants, and lower in pre-frail than in non-frail. Frail and pre-frail older adults obtained lower PEF values than predicted. PEF (% Predicted) was inversely associated with frailty and pre-frailty even after adjustment. Cut-off points were established to discriminate the presence of frailty in older men (PEF≤350L/min; AUC=0.669; sensitivity=76.92%; specificity=52%) and women (PEF≤220L/min; AUC=0.597; sensitivity=71.79%; specificity=46.98%).
conclusionsFrail and pre-frail older adults presented significantly lower PEF than non-frail participants, and these values were lower than predicted. PEF was inversely associated with frailty and pre-frailty. PEF cut-off points can be used as a complementary method to indicate frailty in community-dwelling older adults.
