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

purposeTo evaluate the effect of second transurethral resection (TUR) on oncological outcomes, according to the presence or absence of detrusor muscle in the initial TUR of patients with pTa Grade 3/high grade (G3/HG) tumours, who received at least 1 year of maintenance Bacillus Calmette-Guerin (BCG) therapy. PATIENTS AND

methodsIn this retrospective study, we evaluated the effect of second TUR on oncological outcomes of 93 patients with pTa G3/HG tumours, according to the presence or absence of muscle in the initial TUR. All patients received maintenance BCG therapy according to the SWOG protocol.

resultsMedian follow-up was 36 months. If muscle is present in the initial TUR, a second TUR significantly increased median time to first recurrence, compared to those without a second TUR (77.6 vs 36.9 mos, P = .0086). If muscle is missing in the initial TUR, a second TUR significantly decreased recurrence rate (20% vs 66.7%, P = .002), increased median time to first recurrence (78.9 vs 42.7 mos, P = .0001) and median time to progression (22 vs 7 mos, P = .05), compared to those without a second TUR.

conclusionIn patients with pTa G3/HG tumours, if the muscle is missing in the initial TUR, a second TUR should be performed in order to attain lower recurrence rates and longer median time to recurrence and progression. If the muscle is present in the initial TUR, a second TUR will only increase median time to first recurrence.
