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
backgroundDespite advances in intensive care, sepsis and septic shock still have high morbidity and mortality. Microcirculatory disturbance is a key issue in sepsis, leading to hypoperfusion, hypoxia, and organ failure. The skin is a sensitive indicator of microcirculatory changes and often shows early systemic changes. Recently, bedside skin perfusion indicators such as the mottling score (MS), capillary refill time (CRT), and peripheral perfusion index (PPI) have become common in practice. However, their value in predicting outcomes lacks strong evidence.
methodsA systematic search was conducted across databases, including PubMed, Web of Science, Cochrane Library, EBSCO, China National Knowledge Infrastructure, Wanfang, and VIP, with a search period spanning from the inception of the databases to January 2026. Cohort studies or case-control studies investigating the correlation between skin perfusion parameters and the prognosis of sepsis patients (primary outcomes: 28-day mortality, 14-day mortality, and in-hospital mortality) were included. Two researchers independently performed literature screening, data extraction, and assessment of the Newcastle-Ottawa Scale (NOS) bias risk. A meta-analysis was performed using RevMan 5.4.1 software.
resultsThis study included a total of 22 articles, encompassing 2,727 study subjects. The meta-analysis results demonstrated that: 1) MS was significantly associated with 28-day mortality [odds ratio (OR) = 2.27, 95% confidence interval (CI): 1.79-2.87, P < 0.001] and 14-day mortality (OR = 1.96, 95% CI: 1.32-2.91, P < 0.001); 2) prolonged CRT duration was significantly associated with 28-day mortality (OR = 3.29, 95% CI: 2.08-5.21, P < 0.001) and in-hospital mortality (OR = 2.46, 95% CI: 1.18-5.12, P < 0.001); 3) reduced PPI was significantly associated with 28-day mortality (OR = 5.05, 95% CI: 3.65-6.98, P < 0.001) and in-hospital mortality (OR = 4.56, 95% CI: 3.32-6.26, P < 0.001). Sensitivity analysis confirmed robust results with no significant publication bias.
conclusionThe MS, CRT, and PPI, as bedside and noninvasive skin perfusion parameters, demonstrate significant predictive value for mortality risk in sepsis patients. Integrating these indicators facilitates early clinical identification of high-risk patients, guiding risk stratification, and resuscitation therapy. Future large-sample prospective studies are required to further standardize their assessment protocols and intervention thresholds.
