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
purposeThe purpose of this study is to investigate the influencing factors that may impact the clinical success, jaundice-free time, and overall survival in patients of malignant hilar biliary obstruction (MHBO) treated with a self-expanding metallic stent (SEMS). MATERIALS AND
methodsPatients diagnosed with MHBO and treated with SEMS through percutaneous access from 1 Jul. 2013 to 1 Jul. 2018 were enrolled in this monocentric study. Demographic information, disease baseline measurements, and interventional strategies were collected and examined. Bilirubin was measured 1-3 days before and 3-7 days after stenting using the unit of "μmol/L." The bilirubin reduction ratio was compared between different study groups, which were separated by specific characteristics. Univariate and multivariate analyses were performed to evaluate each characteristic's impact on jaundice-free time (JF) and overall survival time (OS). Statistical analyses were conducted using SPSS 14.0, p < 0.05 indicated significance.
resultsEighty patients were enrolled. Direct bilirubin (DB) and indirect bilirubin (IB) both significantly decreased after stenting (U = 1575.0, p < 0.001; U = 1541.0, p < 0.001). The DB reduction ratio of the "nearby lymph metastases" group was significantly higher (U = 566.0, p = 0.037). The IB reduction ratio in the "single stent" group was significantly higher (U = 554.0, p = 0.018). Sixty-six cases reached jaundice recurrence, the median JF was 6 months, and the 95% confidence interval was 4.411 ~ 7.589 months. Fifty-eight cases ended in death, the median OS was 7 months, and the 95% confidence interval was 5.759 ~ 8.241 months. "Nearby lymph metastases" and "distant metastases" independently impacted OS (OR = 2.344, p = 0.013; OR = 3.239, p = 0.042). "IB reduction ratio" independently impacted both JF and OS (OR = 0.422, p = 0.021; OR = 0.315, p = 0.001).
conclusionThe goal of treatment in patients with MHBO is to recover liver function. However, the overall survival is greatly impacted by the presence of metastases. Managing to obtain adequate liver function recovery may improve the long-term outcomes in affected patients.
