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
aimFrailty, particularly chronic limb-threatening ischemia (CLTI), is a major health concern in patients with peripheral artery disease. CLTI onset can lead to increased frailty and impaired ability to perform daily activities. However, its in-hospital frailty progression in these patients remain poorly defined. This study aims to address this knowledge gap.
methodsWe analyzed 841 CLTI patients (mean age, 75.8 years; 60.2% male) who underwent endovascular therapy (EVT) and were discharged alive from a multicenter registry. Frailty was assessed at admission and discharge using the Clinical Frailty Scale (CFS), categorized as non-frail (1-3), mildly frail (4-5), or advanced frail (6-9). Frailty progression was defined as a transition to a higher frailty category during hospitalization. The predictors of frailty progression during hospitalization were assessed using logistic regression analyses.
resultsOverall, 103 patients (12.2%) experienced frailty progression. Compared to those without progression, these patients had lower left ventricular ejection fraction (LVEF), lower hemoglobin and albumin levels, and more severe wounds. Independent predictors of frailty progression included LVEF ＜40% (odds ratio [OR], 2.02), hemoglobin ＜11 g/dL (OR 1.67), and Wound Grade 3 (OR 2.04). Within 2 years after discharge, the amputation-free survival rate was significantly lower in the progression group than in the non-progression group (42.6% vs. 56.0%; log-rank p = 0.008). The wound healing rate within 2 years after EVT was also significantly lower in the progression group than in the non-progression group (78.2% vs. 88.8%; log-rank p = 0.001).
conclusionsIn-hospital frailty progression was observed in one of the eight patients with CLTI undergoing EVT. Frailty progression was linked to more severe clinical status and worse life and limb outcomes than cases without progression.
