Delayed Postoperative Rehabilitation and Physical Function Recovery Following Late Open Conversion After Endovascular Aneurysm Repair.
Article in Cureus, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background Late open conversion (LOC) after endovascular aneurysm repair (EVAR) is a highly invasive and technically complex procedure. However, postoperative rehabilitation progress and changes in physical function following LOC have not been sufficiently investigated. This study aimed to compare postoperative rehabilitation progress and changes in physical function between patients undergoing LOC after EVAR and those undergoing primary open surgical repair (OSR). Methods This single-center retrospective cohort study included 63 patients who underwent elective primary OSR or LOC between December 2022 and December 2025. The primary outcome was postoperative rehabilitation progress, assessed by the days to first ambulation and independent 100-m walking. Secondary outcomes were changes in physical function, including the Short Physical Performance Battery (SPPB) and six-minute walk distance (6MWD), from before surgery to hospital discharge. Changes in physical function were analyzed using two-way repeated-measures analysis of variance. Results The study included 46 patients in the primary OSR group and 17 in the LOC group. The LOC group required significantly more days to achieve first ambulation (5 (2-8) vs. 2 (2-2) days, p < 0.001) and independent 100-m walking (8 (6-13) vs. 5 (4-6) days, p < 0.001). Significant group-by-time interactions were observed for the SPPB (p = 0.004) and 6MWD (p = 0.048). At hospital discharge, the LOC group had lower SPPB scores (10.2 ± 1.8 vs. 11.4 ± 1.0 points, p = 0.001) and shorter 6MWD (288.9 ± 87.0 vs. 372.2 ± 97.9 m, p = 0.003) than the primary OSR group. Conclusions Compared with patients undergoing primary OSR, those undergoing LOC after EVAR experienced delayed postoperative rehabilitation and greater deterioration in physical function, particularly in lower-extremity physical performance and exercise capacity. These findings may reflect the combined effects of greater surgical invasiveness, procedural complexity, and differences in baseline characteristics.
