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
backgroundThis study aimed to investigate the relationship between the timing of anticoagulation initiation and clinical outcomes in critically ill patients with sepsis-induced coagulopathy (SIC).
methodsWe conducted a retrospective cohort study using the MIMIC-IV database. Adult patients diagnosed with SIC (ISTH-SIC score ≥ 4) and receiving anticoagulation therapy during their ICU stay were included. Anticoagulation therapy was defined as administration of unfractionated heparin, low-molecular-weight heparin, vitamin K antagonists, or direct oral anticoagulants, as captured in medication records; additionally, a heparin-only analysis was performed given its predominant use in this population. Patients were stratified into early (≤ 48 hours post-ICU admission) or delayed (> 48 hours) anticoagulation groups. Baseline characteristics were balanced using propensity score matching (PSM). Primary outcomes included 28-day, 60-day, and 90-day mortality. Cox proportional hazard models were applied to assess survival differences across subgroups.
resultsAmong 12 738 eligible patients, 10 689 received early anticoagulation and 2049 received delayed treatment. After PSM (n = 3986), delayed anticoagulation was associated with significantly lower 28-day mortality (15% vs 19%, P < 0.001), and similar reductions were observed at 60 and 90 days. Kaplan-Meier survival curves showed significantly better survival in the delayed group (P < 0.001). Subgroup analyses revealed that the survival benefit was more pronounced in patients aged >65 years, those without acute kidney injury (AKI), platelet count ≥ 100 × 109/L, Sequential Organ Failure Assessment score ≥ 6, and those treated with unfractionated heparin.
conclusionsAmong critically ill patients with SIC, delayed initiation of anticoagulation was independently associated with improved short- and medium-term survival. These findings support a phenotype-guided, time-stratified approach to anticoagulation in sepsis and highlight the need for prospective trials to validate optimal timing strategies.
