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
Whether preceding transient ischemic attack (TIA) can provide neuroprotective benefits in subsequent acute ischemic stroke (AIS) caused by large vessel occlusion remains unclarified. This study aimed to investigate the association between preceding TIA and functional outcomes in AIS patients with endovascular therapy (EVT). Eligible patients were divided into TIA and non-TIA groups according to whether they experienced TIA within 96 hours prior to stroke. Two groups were balanced using propensity score matching (PSM) analysis at a 1:3 ratio. Onset stroke severity and 3-month functional independence were evaluated. A total of 887 patients were included. After PSM, 73 patients with and 217 patients without preceding TIA were well matched. Onset stroke severity was not different between the groups (p > 0.05). However, the TIA group had a lower systemic immune-inflammation index (SII) (median, 1091 versus 1358, p < 0.05). Preceding TIA was significantly associated with 3-month functional independence (adjusted odds ratio, 2.852; 95% confidence interval [CI], 1.481-5.495; adjusted p < 0.01). The effects of preceding TIA on functional independence were partially mediated by SII (average causal mediation effects 0.02; 95% CI, 0.001-0.06, p < 0.05). In AIS patients treated by EVT, preceding TIA within 96 hours was associated with three-month functional independence but not with reduced onset stroke severity.
