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

objectiveAbnormal expression of several biomarkers might predict disease prognosis and response to chemotherapy in patients with epithelial ovarian cancer (EOC). However, the published data are inconsistent.

methodsEligible studies that investigated the association between survival or response to platinum-based chemotherapy in EOC and the expression status of Bcl-2, EGFR, GST, LRP, p16, p21, P-gp and TNF-α were identified by an electronic search of PubMed and Embase. The measures of interest were hazard ratio (HR) for survival or risk ratio for chemotherapy response. A meta-analysis was performed using the fixed-effect or random-effect models.

resultsThe number of eligible studies analyzed was 27 for Bcl-2, 22 for EGFR, 29 for GST, 12 for LRP, 16 for p16, 22 for p21, 27 for P-gp and three for TNF-α. A meta-analysis showed that high EGFR and P-gp expression was associated with poor overall survival (OS) (pooled adjusted HR = 1.826 and HR = 1.822). Only high GST expression was associated with improved OS (HR = 0.780). Furthermore, high p16 and P-gp expression was associated with poor progression-free survival (PFS) (HR = 1.550 and HR = 2.136). High GST expression was associated with improved PFS (HR = 0.689). Among these factors, only LRP, P-gp and TNF-α were associated with response to platinum-based chemotherapy.

conclusionsThe markers we analyzed are unlikely to be useful as predictors of prognosis and response to platinum-based chemotherapy in EOC patients in clinical practice.
