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

purposeTonsillectomy is one of the most common surgical procedures in otorhinolaryngology. Hemorrhage in the postoperative period has an incidence of up to 20% and is a potentially fatal complication. We aim to assess the incidence of hemorrhage after tonsillectomy in our institution, and to evaluate and identify the possible associated risk factors.

methodsThis retrospective study included 897 patients who underwent tonsillectomy between January 2015 and December 2018, 50.7% women and 49.3% men, aged between 2 and 83 years. No coagulopathies were identified. Comparison of age, gender, surgical indication, coagulation profile, concomitant adenoidectomy, surgical technique, surgeon's experience and hemostasis method between groups with and without post-operative bleeding was made.

resultsOur incidence of post-tonsillectomy hemorrhage was 6%. Most patients (83.3%) had secondary bleeding (> 24 h after surgery). In 22.2% of the bleeding cases, it was necessary to revise the hemostasis in the operating room. Adulthood (age ≥ 18 years) (p < 0.001), INR values ≥ 1.2 (p = 0.014), aPTT values ≥ 35 s (p = 0.001), as well as concomitant adenoidectomy (p < 0.001) were the predictors of post-tonsillectomy bleeding.

conclusionRecognition of adult age, INR ≥ 1.2, aPTT ≥ 35 s and concomitant adenoidectomy as risk factors can be useful in identifying the patients at higher risk for bleeding complications.
