Delaying surgery by more than 10 weeks after long-course neoadjuvant radiotherapy in locally advanced rectal cancer patients improves pathologic complete response.

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
backgroundWe currently do not know the optimal time interval between the end of chemoradiotherapy and surgery. Longer intervals have been associated with a higher pathological response rate, worse pathological outcomes and more morbidity. The aim of this study was to evaluate the effect and safety of the current trend of increasing time interval between the end of chemoradiotherapy and surgery (< 10 weeks vs. ≥ 10 weeks) on postoperative morbidity and pathological outcomes. This study analyzed 232 consecutive patients with locally advanced rectal cancer treated with long-course neoadjuvant chemoradiotherapy from January 2012 to August 2018. 125 patients underwent surgery before 10 weeks from the end of chemoradiotherapy (Group 1) and 107 patients underwent surgery after 10 or more weeks after the end of chemoradiotherapy (Group 2). Results have shown that wait for ≥ 10 weeks did not compromise surgical safety. Pathological complete response and tumor stage was statistically significant among groups. The effect of wait for ≥ 10 weeks before surgery shown higher tumor regression than the first group (Group 1, 12.8% vs Group 2, 31.8%; p < 0.001). On multivariate analysis, wait for ≥ 10 weeks was associated with pathological compete response. Patients from the second group were four time more likely to achieve pathologic complete response than patients from the first group (OR, 4.27 95%CI 1.60-11.40; p = 0.004). Patients who undergo surgery after ≥ 10 weeks of the end of chemoradiotherapy are four time more likely to achieve complete tumor remission without compromise surgical safety or postoperative morbidity.
