A slide review of diagnostic pathologic tissue obtained from 364 bladder cancer cases, identified through the Iowa Surveillance, Epidemiology, and End Results (SEER) Program in 1983, classified 97 (26.6%) of these cases as invasive bladder cancers. These findings contrasted sharply with the Iowa SEER Program classification that coded 289 (79.4%) of these cases as invasive bladder cancers. These results were validated further by the hazard ratio of 4.54 (95% confidence interval, 2.57 to 8.03) among invasive relative to noninvasive bladder cancer cases when the slide review findings were used. In contrast, the hazard ratio was only 1.70 (95% confidence interval, 0.76 to 3.79) when the Iowa SEER Program findings were used. The traditional method used by the National Cancer Institute's SEER Program to deal with this problem is described and its implications are discussed.
This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 01 October 2019.
All research outputs
#9,389,623
of 27,377,461 outputs
Outputs from JNCI: Journal of the National Cancer Institute
#4,575
of 8,323 outputs
Outputs of similar age
#5,989
of 18,989 outputs
Outputs of similar age from JNCI: Journal of the National Cancer Institute
#16
of 37 outputs
Altmetric has tracked 27,377,461 research outputs across all sources so far. This one is in the 42nd percentile – i.e., 42% of other outputs scored the same or lower than it.
So far Altmetric has tracked 8,323 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 21.3. This one is in the 22nd percentile – i.e., 22% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 18,989 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 7th percentile – i.e., 7% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 37 others from the same source and published within six weeks on either side of this one. This one is in the 5th percentile – i.e., 5% of its contemporaries scored the same or lower than it.
