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
introductionTumours in a solitary kidney pose challenges in management. Metastatic tumours and those in difficult locations complicate treatment further. The advent of immunotherapy has shed new light on the management of such tumours. We present a series of three cases treated with nephron-sparing surgery following neoadjuvant immunotherapy and compare the outcomes with patients who underwent robotic partial nephrectomy in a solitary kidney.
methodsWe present the outcomes of three patients with solitary kidney tumours who underwent delayed nephron-sparing surgery following good response to immunotherapy. All patients had solitary kidney following a previous nephrectomy, two of which were nonmetastatic but, due to size/location, not amenable to primary treatment; the third patient had metastatic disease and responded to immunotherapy. Two patients underwent robotic partial nephrectomy and one opted for cryotherapy. We compared the preoperative, intraoperative and postoperative parameters of the two patients who underwent robotic cytoreductive partial with patients who underwent robotic partial nephrectomy in a solitary kidney.
resultsOut of 231 partial nephrectomy patients in our centre, 2 underwent cytoreductive partial nephrectomy and 5 underwent solitary partial nephrectomy. There was no statistically significant difference in the patient demographics in the two groups. Patients in both groups had comparable operative time, warm ischaemia time, blood loss and length of stay. Two of the five patients in the non-cytoreductive robotic partial nephrectomy had Clavien Dindo 1 complications compared with one patient in the robotic cytoreductive partial nephrectomy group. This was not statically significant.
conclusionNeoadjuvant immunotherapy can play a valuable role in shrinking renal tumours in solitary kidneys to facilitate robotic partial nephrectomies. There were no significant differences in the intra- and postoperative parameters in patients who underwent cytoreductive partial nephrectomy when compared with patients undergoing robotic solitary partial nephrectomy.
