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

BACKGROUND AND

objectivesCap-assisted endoscopic sclerotherapy (CAES) via a long needle optimizes the visualization of operation field and enables precise injection of sclerosant, yet evidence regarding its application in high-grade internal hemorrhoids (HDs) remains limited. This study aims to evaluate the efficacy and safety of CAES therapy for bleeding-predominant grade III symptomatic internal HDs, and explore potential risk factors associated with postoperative bleeding persistence and recurrence.

methodsThis single-arm retrospective observational study included 82 patients with bleeding-predominant grade III internal HDs who underwent a single CAES procedure by the injection of liquid polidocanol via a long needle. Treatment efficacy was assessed at 3 months post-CAES using the conventional Hemorrhoid Disease Severity Score (HDSS; based on the frequency of symptoms, including bleeding) and the score of the intensity dimension of the bleeding symptom. Bleeding recurrence was monitored during follow-ups. Logistic regression analysis was employed to explore potential risk factors associated with bleeding outcomes.

results(1) The overall efficacy rate was 85.4%. The effective rates for bleeding and prolapse symptoms were 96.3% and 58.2%, respectively. (2) During a follow-up of 24 months, the bleeding recurrence rate was 25.3% (20/79). (3) Exploratory logistic regression analysis suggested that a high pre-CAES bleeding intensity score (odds ratio [OR] = 2.887, p = 0.030) was significantly associated with non-excellent outcome (i.e., persistent bleeding); meanwhile, a high pre-CAES bleeding intensity score (OR = 3.981, p = 0.012) and a high post-CAES bleeding frequency score (OR = 3.803, p = 0.006) were significantly associated with post-CAES bleeding recurrence. (4) No severe complications were reported.

conclusionsCAES with long-needle injection of polidocanol may serve as an effective and safe therapeutic option for managing bleeding symptom in grade III internal HDs. The higher bleeding-associated scores, which encompass both bleeding frequency and intensity, may represent potential risk factors for persistent or recurrent bleeding after the CAES procedure.
