1 · What the graph read from it

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.

2 · The registry

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

backgroundThe prognostic significance of serum lactate dehydrogenase (LDH) level in thymic carcinoma (TC) remains unclear. Therefore, we evaluated the role of pretreatment serum LDH level in the prognosis for TC in this study.

methodsSixty consecutive surgical patients were analyzed in this study with pathologic confirmed TC in Sun Yat-sen University Cancer Center from June 1996 to June 2014.

resultsThe cut-off value of LDH was 210.50 IU/L. In both univariate analysis and multivariable analysis, only pretreatment serum LDH level (P=0.027) and pathological Masaoka stage (P=0.041) were associated with overall survival (OS). In univariate analysis, pretreatment serum LDH level, tumor size, postoperative radiotherapy (PORT) and pathological Masaoka stage were associated with disease-free survival (DFS) (all P<0.050). Multivariable analysis showed that LDH level (P=0.001), PORT (P=0.001) and pathological Masaoka stage (P=0.038) were independently prognostic factors of DFS. This study also revealed that male patients and larger tumor size had a significantly higher rate of elevated pretreatment serum LDH level than in the other groups.

conclusionsIn conclusion, pretreatment serum LDH level was an independent prognosis factor of OS and DFS for patients with TC.
