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

purposeMinimally invasive surgery for low rectal cancer is technically demanding because of the restricted pelvic access and visualization. Transanal total mesorectal excision (TaTME) was developed to address these challenges, but concerns remain regarding its safety and oncological validity. We conducted this study to compare the short-term surgical outcomes and long-term oncological results of TaTME with those of conventional laparoscopic TME (LapTME).

methodsThe subjects of this retrospective review were 154 patients who underwent radical resection for low rectal cancer between 2009 and 2023. Patients were categorized into a TaTME group (n = 95) and a LapTME group (n = 59). Propensity score matching (PSM) was performed to minimize selection bias, yielding 44 matched pairs. We then compared the surgical and oncological outcomes of the two groups.

resultsTaTME was associated with significantly shorter operative times (330 vs. 394 min; P = 0.020), less blood loss (0 g vs. 68 g; P < 0.001), and fewer postoperative complications (Clavien-Dindo ≥ II: 25.0% vs. 54.8%; P < 0.001), but a higher rate of diverting ileostomy (65.9% vs. 38.6%; P = 0.018). Long-term oncological outcomes, including survival and local recurrence, were comparable.

conclusionTaTME improves perioperative outcomes without compromising oncological safety. With proper training and technique, TaTME is a safe and effective option for low rectal cancer surgery.
