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
backgroundThe purpose of this phase I study of the dose escalation of oxaliplatin in combination with oral S-1 and pelvic radiation preoperatively for poor-risk lower rectal cancer was to determine the dose-limiting toxicity (DLT) and recommended dose of oxaliplatin.
methodsPatients with cT4 and lateral pelvic lymph node metastasis, and without distant metastasis (cM0), were treated with weekly oxaliplatin, oral S-1 40 mg/m(2) twice daily for 5 days a week, and radiation. A total of 5 weekly doses of oxaliplatin were planned. RT was administered to a total dose of 50.4 Gy in 28 fractions.
resultsWe enrolled 11 patients between December 2009 and January 2012. DLTs were observed at dose level 1 (50 mg/m(2)) in two patients, one of whom experienced grade 3 aspartate aminotransferase elevation and a grade 3 alanine aminotransferase increase, and the other developed grade 4 hypokalemia and a grade 3 alanine aminotransferase increase. Five patients at dose level 2 (60 mg/m(2)) showed no DLTs. The hematological toxicities in all patients were mild and reversible. One patient showed distant metastasis after chemoradiation. Ten of the 11 patients achieved R0 resection by mesorectal resection and lateral lymph node dissection; three of the 10 underwent combined resection of the other organs.
conclusionThis phase I trial of preoperative S-1 in combination with oxaliplatin and radiation for lower rectal cancer with T4 and lateral pelvic lymph node metastasis revealed that the recommended dose of oxaliplatin was 60 mg/m(2) weekly.
