Mortality of older persons with and without abnormalities in the physical examination of arterial system.
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. Not yet cited in PubMed.
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
backgroundAnkle-brachial index (ABI) is a screening tool for peripheral arterial disease (PAD). However, persons with normal ABI may still exhibit abnormalities in the physical examination of arterial system (PHEA).
objectiveIn older persons from the PolSenior study, we aimed to assess the risk of total mortality associated with abnormalities in PHEA in the context of dichotomised ABI.
methodsWe used data from the PolSenior survey and matched them with mortality information from the Polish Census Bureau. We obtained sociodemographic, medical history, and lifestyle data. The PHEA by a geriatrician included carotid, femoral, popliteal, posterior tibial and the dorsalis pedis arterial pulses, and auscultation of aorta, carotid, femoral, and renal arteries. Ankle-brachial index was tibial to brachial SBP ratio. We plotted the stratified Kaplan-Meier curves and used Cox's regression to assess the unadjusted and adjusted influence of PHEA result on time to death.
resultsThe mean (standard deviation, SD) age of 852 persons (46.7% women) was 74.7 (10.6) years. In the ABI < 0.9 group, the PHEA was not associated with mortality. However, in the ABI ≥ 0.9 group, both in unadjusted and adjusted (RHR; 95% CI: 1.08; 1.02-1.16, p = 0.01) Cox regression, PHEA greater by 1 score was associated with mortality. Presence of 4 or more PHEA abnormalities was raising the risk in the ABI ≥ 0.9 group to the level associated with ABI < 0.9.
conclusionsIn the older persons with normal ABI, the greater number of abnormalities during physical examination of arteries may be indicative of higher risk of death.
