Resting respiration rate predicts all-cause mortality in older outpatients.
Article in Aging clinical and experimental research, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundAlthough respiratory rate has been a sensitive predictor for prognosis in acute settings, resting respiratory rate (RRR) is undervalued in chronic care. The clinical significance of RRR among older people is not well documented.
aimWe investigated the association between RRR and all-cause mortality among older outpatients.
methodsA retrospective cohort study exhaustively included patients who had undergone medical checkups in a facility between April 2017 and March 2018 and followed up for at least 2 years. We excluded patients who were less than 60 years of age or had not undergone regular outpatient appointments. Sex, age, smoking habits, history of hospitalization, polypharmacy, long-term care insurance certification status, Mazzaglia index, pulse rate, systolic blood pressure, and Charlson Comorbidity Index were measured at the baseline medical checkup. Survival was confirmed by chart review and by contacting physicians in charge. The risk ratios were estimated by converting the odds ratios derived from the multivariable logistic regression models.
resultsOf the 853 patients who underwent baseline checkups, 749 were enrolled in the analyses; death occurred in 53 patients (7.1%), with no loss to follow-up. The RRR was independently associated with all-cause mortality after adjusting for covariates [adjusted risk ratio of RRR per 1 bpm = 1.14, 95% confidence interval (CI): 1.06 - 1.22]. DISCUSSION: Given the independent association of RRR for existing predictors, this simple index seems worthy of consideration in further studies aimed at defining its predictive role in older people and in different settings.
conclusionRRR was independently associated with all-cause mortality.
