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
ObjectiveThe D-dimer to fibrinogen ratio (DFR) has been suggested as a biomarker reflecting disease severity in multiple conditions. This study investigated the relationship between DFR and 3-month outcomes in acute ischemic stroke (AIS) patients undergoing intravenous thrombolysis.MethodsConsecutive AIS patients treated with intravenous thrombolysis were enrolled. Clinical and laboratory data were collected, and functional outcomes were assessed at 3 months using the modified Rankin Scale (mRS), with scores of 3-6 defined as unfavorable. Receiver operating characteristic (ROC) analysis identified the optimal DFR cutoff, and multivariable logistic regression determined predictors of unfavorable outcomes.ResultsAmong 184 patients included, 66 (35.9%) experienced unfavorable outcomes. Compared with patients with favorable outcomes, those with unfavorable outcomes had higher fasting blood glucose, D-dimer, fibrinogen, DFR, and baseline NIHSS scores (P < 0.05), and lower high-density lipoprotein (HDL) levels (P < 0.05). The optimal DFR cutoff for predicting 3-month outcomes was 0.146. Three multivariable logistic regression models were constructed because of the potential collinearity among D-dimer, fibrinogen, and DFR. After adjustment for confounding factors, DFR remained independently associated with unfavorable outcomes (OR = 3.827, 95% CI: 1.289-11.365, P = 0.016).ConclusionIn summary, our findings suggest that DFR is associated with outcomes in AIS patients receiving intravenous thrombolysis.
