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
RABEX-5 has been studied in various solid tumors, but its role in combined small cell lung cancer (C-SCLC) remains unknown. This study aimed to investigate the expression, the potential relevance to clinicopathological characters and prognostic significance of RABEX-5 in patients with C-SCLC. Fifty-two C-SCLC patients who received radical surgery were enrolled in our study. The clinicalpathological data and survival time were reviewed. The mRNA and protein expression of RABEX-5 from the paired tumor tissues and adjacent normal tissues were determined, and its relationship with clinicalpathological variables and prognosis was analyzed. Univariate and multivariate analyses were performed to investigate the prognostic significance of RABEX-5 for C-SCLC. The mRNA and protein expression level of RABEX-5 was significantly elevated in C-SCLC tissues. The increased RABEX-5 protein expression was correlated with clinical stage (p = 0.011) and tumor recurrence (p = 0.006). The median OS and DFS was significantly shorter in the high RABEX-5 expression group compared to low RABEX-5 expression group (OS: 12.0 vs. 21.7 months, p = 0.014; DFS: 6.7 vs. 11.8 months, p = 0.005). Multivariate Cox analysis indicated that high RABEX-5 protein expression was an independent prognostic factor for OS and DFS (p < 0.001). RABEX-5 is a potential useful indicator and predicts a poor long-term prognosis for C-SCLC, which should be considered in defining the prognosis with other well-known prognosticators in C-SCLC patients.
