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
The KRAS oncogene was among the first genetic alterations in colorectal cancer (CRC) to be discovered. Moreover, KRAS somatic mutations might be used for predicting the efficiency of anti-epidermal growth factor receptor therapeutic drugs. Because the KRAS mutations are similar in the primary CRC and/or the CRC metastasis, KRAS mutation testing can be performed on both specimen types. The purpose of this study was to investigate the clinical advantage of using a KRAS pathway-associated molecule analysis chip to analyze CRC patients treated with cetuximab. Our laboratory developed a KRAS pathway-associated molecule analysis chip and a weighted enzymatic chip array (WEnCA) technique, activating KRAS detection chip, which can detect KRAS mutation status by screening circulating cancer cells in the bloodstream. We prospectively enrolled 210 stage II-III CRC patients who received adjuvant oxaliplatin plus infusional 5-fluorouracil/leucovorin (FOLFOX)-4 chemotherapy with or without cetuximab. We compared the chip results of preoperative blood specimens with disease control status in these patients. Among the 168 CRC patients with negative chip results, 119 were treated with FOLFOX-4 plus cetuximab chemotherapy, and their relapse rate was 35.3 % (42/119). In contrast, the relapse rate was 71.4 % among the patients with negative chip results who received FOLFOX-4 treatment alone (35/49). Negative chip results were significantly correlated with better treatment outcomes in the FOLFOX-4 plus cetuximab group (P < 0.001). We suggest that the activating KRAS detection chip is a potential tool for predicting clinical outcomes in CRC patients following FOLFOX-4 treatment with or without cetuximab therapy.
