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
Objective: Patients with peripheral arterial disease (PAD) undergo revascularization to improve physical function, yet meaningful improvement has not been defined. This study aims to define a threshold for improvement in patient-reported physical function (PROMIS-PF) and establish factors predictive of improvement following lower extremity revascularization. Methods: This study is a single-center retrospective cohort analysis of adults undergoing elective revascularization for PAD 2016-2023 who had PROMIS-PF scores. Anchor- and distribution-based approaches were used to triangulate a single minimal clinically important difference (MCID) value representing an improvement in PROMIS-PF after revascularization. The anchor question was a general health question. A least absolute shrinkage selection operator (LASSO) selected for relevant variables that predict if a patient will reach the MCID that were inputted into generalized linear mixed model regression. Results: Forty five percent of patients (N=60/132) had an anchor question that changed over time (improved or declined) with a corresponding PROMIS-PF anchor-based MCID value of 5.2 (±8.3). The distribution-based MCID was calculated from 62 patients with a PROMIS-PF standard deviation (SD) of 8.4, corresponding to a distribution-based MCID (1/2 × SD) of 4.2. The MCID values from both approaches converged on a conservative MCID estimate of ≥ 5. Forty percent of patients (N=25/62) met MCID following revascularization. Patients with higher baseline PROMIS-PF scores and more advanced age are less likely to meet MCID (OR 0.81, 95%CI 0.71 - 0.93, OR 0.94, 95%CI 0.88 - 1.00, respectively). However, only 41% of patients who had an improvement in ankle brachial index (ABI) value also met the MCID. Conclusions: A 5-point change in PROMIS-PF represents a meaningful improvement after revascularization for patients with PAD. Surgical technical success with a clinically meaningful improvement in ABI does not predict a corresponding improvement in function. Whether patients achieve functional improvement after revascularization depends on their baseline function score and age.
