Transient variations in the serum concentrations of cell adhesion molecules following retroperitoneal laparoscopic and open radical nephrectomy for localized renal-cell carcinoma.
Trial report in Journal of endourology, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeTo evaluate differences in the serum concentrations of cell adhesion molecules (CAMs) after retroperitoneal laparoscopic and conventional open radical nephrectomies for localized renal-cell carcinoma (RCC). PATIENTS AND
methodsA total of 62 patients with stage T(1)N(0)M(0) RCC were randomized to either a retroperitoneal laparoscopic radical nephrectomy group (n=31) or an open group (n=31). Serum levels of soluble cluster of differentiation 44 splice variant 6 (sCD44v6), soluble intercellular adhesion molecule-1 (sICAM-1), soluble vascular cell adhesion molecule-1 (sVCAM-1), and soluble epithelial cadherin (sE-cadherin) were determined independently by enzyme linked immunosorbent assay (ELISA) preoperatively, and on postoperative days 1 and 5. In addition, follow-up results were compared.
resultsOn postoperative day 1, sCD44v6, sICAM-1, and sVCAM-1 levels increased significantly compared with preoperative levels in both groups (P<0.05). sE-cadherin levels decreased compared with preoperative levels in both groups without statistically significant differences (P>0.05). sCD44v6 levels in the retro-laparoscopy group were significantly higher than in the open group (P<0.05), while sICAM-1, sVCAM-1, and sE-cadherin levels showed no statistically significant differences between both groups (P>0.05). On postoperative day 5, all parameters in both groups were similar to preoperative values (P>0.05). Follow-up ranged from 7 to 18 months postoperatively in all 62 patients, with a 100% cancer-specific survival rate in each group.
conclusionAlthough postoperatively higher serum concentrations of CAMs in both groups and significantly elevated sCD44v6 in the retro-laparoscopy group may be facilitated, the differences in CAMs between both groups are small and transient. Together with the similar follow-up results, this further supports previous studies that failed to show a difference in the oncologic outcomes between open and laparoscopic radical nephrectomy and provides a probable molecular mechanism.
