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

purposeObstructive colorectal cancer has a poor prognosis. Self-expanding metallic stents (SEMSs) and transanal colorectal tubes (TCTs) are used as a bridge to surgery (BTS). However, comparative evidence is limited. This study compared the short-term outcomes of SEMS and TCT placement using a nationwide database.

methodsWe identified 19,564 patients who underwent colectomy after SEMS or TCT placement for cT3-4N0-2M0 colon cancer between 2012 and 2022 using the Diagnosis Procedure Combination database. After exclusion, 16,033 patients were analyzed. Propensity score matching generated 5,203 matched pairs for analysis. Outcomes were compared using conditional logistic regression and linear fixed-effect models.

resultsThe overall stoma rate was significantly lower in the SEMS group than in the TCT group (odds ratio [OR], 0.29; 95% confidence interval [CI], 0.23-0.35). SEMS placement was associated with reduced postoperative abdominal drainage (OR, 0.31; 95% CI, 0.28-0.35) and reoperation (OR, 0.25; 95% CI, 0.20-0.31) rates. The total hospital stay was shorter in the SEMS group (regression coefficient, - 3.5 days; 95%CI, - 4.3 to - 2.6).

conclusionsThis nationwide cohort study showed that SEMS placement significantly reduced perioperative stoma construction compared with TCT placement. A lower frequency of stoma construction, postoperative abdominal drainage, and reoperation was associated with shorter total hospital stays.
