Comparative analysis of different apoptosis detection methods in human testicular cancer.
Article in Urological research, 2004. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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.
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
In situ end-labeling (ISEL) of internucleosomal 3' DNA strand breaks and the morphological proof of nuclear chromatin condensation are two widely used methods to investigate and quantify apoptosis. However, it is still unclear whether both processes are linked with each other and if quantifying apoptosis by both methods leads to comparable results. Therefore, internucleosomal DNA fragmentation and chromatin condensation were measured simultaneously on double-fluorescence-labeled sections of 62 testicular tumors (47 nonseminomatous tumors and 15 seminomas) using immunofluorescence microscopy. Different apoptotic indices (AI), based on DNA fragmentation and/or morphological criteria were determined. The AI were quantified. Morphologically obtained AI ranged between 1.99% for non-seminomatous tumors and 0.88% for seminomas. The detection of DNA fragmentation values ranged between 8.15% for non-seminomatous tumors and 2.70% for seminomas. Only about 30% of all apoptotic cells could be detected with the morphological method compared to 80% using ISEL in both tumor entities. Therefore, the equivalence of investigations using different apoptosis detection methods in human testicular cancer seems questionable.
