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

objectiveTo examine factors associated with bone scan use in patients undergoing radical cystectomy and to assess trends in use over time. MATERIALS AND

methodsUsing Surveillance, Epidemiology, and End Results-Medicare data, we identified 5573 patients who underwent radical cystectomy from 2004 to 2011. The primary outcome was completion of a bone scan within 6 months prior to surgery. Demographic, regional, and clinicopathologic predictors of bone scan use were examined using a mixed logit model with health service area as a random effect.

resultsAmong radical cystectomy patients, 1754 (31%) completed a preoperative bone scan. Urologists ordered most of these studies (69%). The adjusted probability of a patient undergoing a bone scan decreased from 0.40 in 2004 to 0.29 in 2011 (P = .01). Compared with patients in the northeast region, those in the south, central, and west regions were less likely to have a bone scan (P <.001). Compared with those with stage ≤T1, patients with higher stage disease were more likely to have a bone scan (P <.001). Among the highest volume surgeons, there was significant variation in the proportion of patients who completed preoperative bone scans (P < .001).

conclusionDespite a recent decline, bone scans are used frequently in the preoperative staging of bladder cancer. Although some clinical factors are associated with bone scan use, significant regional and provider variation suggest areas to improve standardization of practice.
