Lack of Bax expression is associated with irinotecan-based treatment activity in advanced colorectal cancer patients.

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
backgroundCurrently, first-line chemotherapy in advanced colorectal cancer is not tailored on predictive biomarkers. Bax proapoptotic protein may correlate to chemosensitivity and differential response to irinotecan or oxaliplatin-based combinations.
methodsBax expression was assessed by immunohistochemistry in 49 advanced colorectal cancer patients enrolled at our institution from 2002 to 2004 within a multicenter, phase II, randomized trial of first-line UFT/leucovorin/irinotecan (TEGAFIRI) versus UFT/leucovorin/oxaliplatin (TEGAFOX).
resultsBax-positive and negative samples were 49 and 51 %. Response was significantly lower in Bax positive (25 %) as compared to Bax negative (56 %) (Odds ratio = 0.26; p = 0.03). No significant difference was noted in TEGAFOX subgroup; in TEGAFIRI arm, responses were lower in Bax positive (18 %) than Bax negative (67 %) (Odds ratio = 0.11; p = 0.03). No difference in terms of progression-free and overall survival was observed according to Bax.
conclusionBax-negative colorectal cancer may identify a specific phenotype of patients with significantly higher chance to respond to doublet irinotecan-based chemotherapy.
