Article in The oncologist, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map.

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.

Abstract
backgroundPD-1/PD-L1 immune checkpoint inhibitors (ICIs) have demonstrated activity in the post-platinum and platinum-ineligible settings for advanced urothelial carcinoma (aUC). As only around 50% of patients with aUC can tolerate platinum-containing treatment, treatments combining first-line ICIs with non-platinum drugs are urgently needed. Therefore, we assessed the safety and efficacy of the anti-PD-L1 monoclonal antibody Socazolimab in combination with nab-paclitaxel as first-line therapy in aUC (NCT04603846).
methodsThis was a multi-center, single-arm, phase Ib study that enrolled patients with treatment-naive aUC. Patients received Socazolimab (5 mg/kg) and nab-paclitaxel (260 mg/m2) Q3w. The primary endpoint was safety and tolerability of the combination regimen. Second endpoints were the objective response rate (ORR) and progression-free survival.
resultsBetween September, 2020 and September, 2021, 20 patients with urothelial carcinoma were enrolled, arising from renal pelvis (5), bladder (8), and ureter (7). After a median follow-up of 17 months, the median number of treatment cycles was 12. No patients had dose limiting toxicity. All patients had treatment-related adverse events (TRAEs), most of which were grade 1 or 2. The common TRAEs (≥20%) were peripheral neurotoxicity, alopecia, rash, increased ALT, weight loss, weakness, pruritus, increased AST, increased γGT, increased ALP, neutropenia, emesis, and anorexia. Nine patients (45%) developed grade 3 TRAEs including peripheral neurotoxicity (30.0%), increased ALT (10.0%), and increased γGT (5.0%). Two patients (10%) discontinued treatment because of grade 3 mouth ulcer (n = 1) and grade 2 lung fibrosis (n = 1). No grade 4-5 TRAEs were observed. Among the 17 patients who had received at least one tumor assessment, ORR was 58.8% (95% CI, 32.9%-81.6%) and the median progression-free survival was 8.3 months (95% CI, 5.2-19.5). The median duration of response was 13.3 months (95% CI, 2.0-20.1), and the overall survival was 19.5 months (95% CI, 11.2-not reached).
conclusionSocazolimab combined with nab-paclitaxel has shown good safety and promising antitumor activity as first-line therapy in patients with advanced urothelial carcinoma.
