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
purposeThe retrospective study was to explore the effectiveness and safety of GemOx (gemcitabine, oxaliplatin) plus sintilimab (belongs to the class of drugs known as immune checkpoint inhibitors, particularly targeting the PD-1 receptor) in relapse or refractory nodal PTCLs.
methodsPatients with nodal PTCL who initiated salvage therapy with sintilimab and GemOx between January 2020 to September 2021 were identified from the database of the hematology department of the Second Affiliated Hospital of Zhejiang University School of Medicine. All patients received 2-4 cycles (3 weeks/cycle) of treatment of sintilimab (200 mg, I.V, D1) in combination with GemOx. Treatment response was assessed every six weeks during the salvage treatment phase. Eligible patients received maintenance therapy according to the investigator's decision. Follow-ups were routinely conducted every three months.
results31 patients with r/r nodal PTCLs were enrolled, including 23 PTCL-NOS, 4 AITL, and 4 ALCL. 21 (67.7%) patients received at least two lines of therapy. 71.0% (95% CI, 53.4%-83.9%) of patients documented objective response of 2-4 cycles of sintilimab plus GemOx therapy, including 9 complete response and 13 partial response. 21 (67.7%) patients received consolidation therapy, including 5 autologous stem-cell transplantation and 12 histone deacetylase inhibitors. After a median 25.6 months follow-up, the median PFS was 22.0 (95% CI,11.8-24.7) months, and the median OS was 26.2 (95% CI, 24.4 -NA) months. 29 (93.5%) patients experienced at least one adverse event, and 26 (83.9% patients only had mild (grade 1-2) AEs.Univariable Cox regression showed the progression risk of AITL is 22.7 (3.9- 131.0, p < 0.01) times of PTCL-NOS, while the HR of ALCL was 1.14 (0.33-3.96,p = 0.833).
conclusionSintilimab plus GemOx showed encouraging activity and manageable toxicity for patients with r/r PTCL.
