1 · What the graph read from 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.

2 · The registry

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

purposeTo explore the anatomical features of left iliac vein (LIV) in non-thrombotic venous leg ulcers (VLUs) and to identify the impact of these anatomical features on VLUs based on computed tomography venography (CTV).

methodsThis is a retrospective, single-center study of a database (2021-2023) of 431 patients with non-thrombotic chronic venous insufficiency. According to CEAP clinical (C) classifications, cases of C6 and C2 were included for analysis as case and control groups. Based on CTV data, variables that reflected the anatomical characteristics of LIV and lower lumbar degenerative changes were compared between the two groups. Multivariate logistic regression analysis was performed to evaluate impact of the anatomical features of LIV on VLUs.

resultsA total of 116 patients (group C6 (n = 33) and C2 (n = 83)) were included. Variables including anterior lumbar vertebral osteophytes (ALVO), minimum diameter of LIV, the number of sites of LIV stenosis, proportion of cases with percentage compression of LIV ≥ 75%, proportion of cases with triple or dual LIV stenosis showed significant difference between the two groups (all P ˂0.05). Logistic regression analysis showed ALVO [odds ratio (OR) = 3.852, P = 0.025], number of sites of LIV stenosis [OR = 2.654, P = 0.027] and minimum diameter of LIV [OR = 0.585, P = 0.010] were all significant for VLUs.

conclusionsThe factors of ALVO and number of sites of LIV stenosis were risk factors, whereas minimum diameter of LIV was a protective factor for VLUs. This provided a direction for preoperative planning of non-thrombotic LIV stenting.
