Usefulness of ultrasound-guided intraluminal approach for long occlusive femoropopliteal lesion.
Observational study in Heart and vessels, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
To investigate the usefulness of ultrasound-guided (USG) intraluminal approach for femoropopliteal (FP) lesion. 64 patients (73 limbs) with de novo long occlusive (> 15 cm) FP lesions underwent USG intralumial approach from April 2012 to October 2016. Periprocedural intravascular ultrasound findings were collected. Clinical outcome and predictors of restenosis after USG intraluminal approach for de novo long occlusive FP lesion were investigated. Among the study participants, 34% were female, 50% had diabetes mellitus, and 10% received hemodialysis. Lesion and chronic total occlusion (CTO) lengths were 222 ± 55 mm and 201 ± 55 mm, respectively. Procedural success was achieved in 72 lesions (99%). Distal puncture was performed in 7 limbs (10%). The proportion of within-CTO intraplaque, subintimal, and medial routes were 87 ± 21%, 9 ± 15%, and 4 ± 11%, respectively. Primary patency was 71% and 69% at 1 and 2 years. Multivariate analysis revealed that within-CTO intraplaque route proportion [hazard ratio (HR) 0.81; 95% confidence interval (CI) 0.67-0.98, p = 0.0339] and lesion length (HR 1.11; CI 1.00-1.22; p = 0.0447) were independent predictors of restenosis.USG intraluminal approach facilitated acquisition of within-CTO intraplaque route in long occlusive FP lesions and could improve clinical outcome.
