Self-reported health status and disease-specific quality of life one year after treatment for peripheral arterial disease in clinical practice.
Observational study in Health and quality of life outcomes, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundVascuQoL-6 (VQ-6) is a disease-specific quality of life (QoL) instrument validated for use in clinical practice and vascular registries before and after treatment for peripheral arterial disease (PAD). To improve future interpretation of self-reported outcome, an unselected cohort was followed through one year to provide observational data after both conservative and invasive treatment.
methodsConsecutive patients with intermittent claudication (IC) or critical limb ischemia (CLI) were included. All patients completed VQ-6 and Short Form-36 (SF-36), and were evaluated with ankle-brachial index (ABI) measurement pre- and post-exercise, a constant load treadmill test and clinical consultation at baseline and after one year. Change statistics and correlation analysis were used to describe self-reported outcome after conservative and invasive treatment for PAD.
resultsOne hundred seventy-one patients with peripheral arterial disease (PAD) were included, 70 (41%) female. 147 (86%) of the patients suffered from IC. 136 (80%) patients had one-year follow up, death, amputation and withdrawal were the major causes of loss to follow-up. Forty-eight patients (35%) evaluated their health to be unchanged compared to one year ago. There was a strong correlation between self-reported general health status based on SF-36 item 2 and VQ-6 summary score (Spearmans rho = - 0.536). Patients admitted to invasive intervention (endovascular or surgery) improved in all domains of SF-36, and in the physical component summary score (SF-36 PCS). Patients admitted to best medical treatment, smoking cessation and walking exercise (conservative group) improved only in the physical domains. There was significant improvement in VQ-6 summary score for both groups, mean 2.20 (95%CI 1.14-3.27) in the conservative group, 4.68 (95%CI 3.67-5.70) in the invasive group. VQ-6 sum score improved more than four points for 56% in the invasive group, 36% in the conservative group.
conclusionsTreatment for symptomatic PAD, both invasive and conservative, improves self-reported health status and disease specific QoL after one year. Interpretation of patient-reported outcome measured with VQ-6 after surgery or endovascular treatment must be seen in light of the improvement from conservative treatment alone.
