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
Conventional treatment of recurrent and metastasized prostate cancer (CaP) remains inadequate; this fact mandates development of alternative therapeutic modalities, such as specific active or passive immunotherapy. Previously, we reported the identification of a novel highly immunogenic HLA-A*0201-restricted Prostatic Acid Phosphatase-derived peptide (PAP-3) by a two-step in vivo screening in an HLA-transgenic (HHD) mouse system. In the present study we aimed at elucidating the efficiency of PAP-3-based vaccine upon active antitumor immunization. To this end we established preventive and therapeutic carcinoma models in HHD mice. The 3LL murine Lewis lung carcinoma clone D122 transduced to express HLA-A*0201 and PAP served as a platform for these models. The HLA-A*0201-PAP-3 complex specific recombinant single chain scFV-PAP-3 antibodies were generated and used to confirm an endogenous PAP processing resulting in PAP-3 presentation by HLA-A*0201. PAP-3 based vaccines significantly decreased tumor incidence in a preventive immunization setting. Therapeutic vaccination of HHD mice with PAP-3 led to rejection of early established tumors and to increase of mouse survival. These results strongly support a therapeutic relevance of the identified CTL epitope upon active antitumor immunization. The newly established carcinoma model presented herein might be a useful tool for cancer vaccine design and optimization.
