1 · What the graph read from it

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.

2 · The registry

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

purposeThis study compared complete response (CR) outcomes between two total neoadjuvant therapy (TNT) strategies for locally advanced rectal cancer: induction chemotherapy followed by long-course chemoradiotherapy (INCT-LCCRT) versus short-course radiotherapy followed by consolidation chemotherapy (SCRT-CNCT).

methodsThe subjects of this retrospective study were 234 patients with clinical stage T3-4NanyM0 low rectal cancer, treated between 2011 and 2022 with TNT and either total mesorectal excision or non-operative management (NOM). CR was defined as pathological CR after resection or sustained clinical CR in NOM. Propensity score matching was applied to adjust baseline differences, resulting in 38 matched pairs. We evaluated CR rates and survival outcomes.

resultsThere were 194 patients treated with INCT-LCCRT and 40 treated with SCRT-CNCT. The INCT-LCCRT group had more advanced disease features, including higher rates of clinical T4 (29.9% vs. 2.5%) and lateral pelvic node metastases (62.4% vs. 10%). The CR rates were comparable in the full cohort (30.9% vs. 30.0%, p = 1) and after matching (34.2% vs. 28.9%, p = 0.81). No significant differences were observed in 3-year relapse-free or local recurrence-free survival.

conclusionsIn the matched cohort of mainly intermediate-risk cases, INCT-LCCRT and SCRT-CNCT demonstrated comparable CR rates and oncological outcomes.
