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

purposeWe sought to determine whether anesthetic type (general vs spinal) would influence cancer recurrence following transurethral resection of bladder tumors. MATERIALS AND

methodsWith institutional ethics board approval we examined the electronic medical records of all patients who underwent transurethral bladder tumor resection for nonmuscle invasive urothelial bladder cancer between 2011 and 2013 at a single tertiary care center. Followup information was gathered on all patients in December 2016. The time to first cancer recurrence and the incidence of cancer recurrence were the main outcome measures.

resultsA total of 231 patients underwent 1 or more transurethral bladder tumor resections between 2011 and 2013. Of the 231 patients 135 received spinal anesthesia and 96 received general anesthesia. On univariable analysis the 135 patients who received spinal anesthesia had a longer median time to recurrence than the 96 who received general anesthesia (42.1 vs 17.2 months, p = 0.014). As anticipated, adjuvant therapies and risk category were associated with recurrence rates (p = 0.003 and 0.042, respectively). On multivariable analyses incorporating a priori variables of nonmuscle invasive bladder cancer risk stratification and postoperative therapies the patients who received general anesthesia had a higher incidence of recurrence (OR 2.06, 95% CI 1.14-3.74, p = 0.017) and an earlier time to recurrence (HR 1.57, 95% CI 1.13-2.19, p = 0.008) than those who received spinal anesthesia. Anesthetic type was not associated with cancer progression or overall mortality.

conclusionsPatients who received spinal anesthesia had a lower incidence of recurrence and a delayed time to recurrence following transurethral bladder tumor resection for nonmuscle invasive bladder cancer. These findings should prompt large-scale prospective studies to confirm this association.
