Randomized Phase II Trial of Cisplatin and Etoposide in Combination With Veliparib or Placebo for Extensive-Stage Small-Cell Lung Cancer: ECOG-ACRIN 2511 Study.
Trial report in Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT01642251 (Phase I and Randomized Phase II Double Blind Clinical Trial of Cisplatin and Etoposide in Combination With Veliparib), which is not on this map. Cited by 102 papers, 6 of them syntheses that pooled it.
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

Abstract
purposeVeliparib, a poly (ADP ribose) polymerase inhibitor, potentiated standard chemotherapy against small-cell lung cancer (SCLC) in preclinical studies. We evaluated the combination of veliparib with cisplatin and etoposide (CE; CE+V) doublet in untreated, extensive-stage SCLC (ES-SCLC). MATERIALS AND
methodsPatients with ES-SCLC, stratified by sex and serum lactate dehydrogenase levels, were randomly assigned to receive four 3-week cycles of CE (75 mg/m
resultsA total of 128 eligible patients received treatment on protocol. The median age was 66 years, 52% of patients were men, and Eastern Cooperative Oncology Group performance status was 0 for 29% of patients and 1 for 71%. The respective median PFS for the CE+V arm versus the CE+P arm was 6.1 versus 5.5 months (unstratified hazard ratio [HR], 0.75 [one-sided P = .06]; stratified HR, 0.63 [one-sided P = .01]), favoring CE+V. The median overall survival was 10.3 versus 8.9 months (stratified HR, 0.83; 80% CI, 0.64 to 1.07; one-sided P = .17) for the CE+V and CE+P arms, respectively. The overall response rate was 71.9% versus 65.6% (two-sided P = .57) for CE+V and CE+P, respectively. There was a significant treatment-by-strata interaction in PFS: Male patients with high lactate dehydrogenase levels derived significant benefit (PFS HR, 0.34; 80% CI, 0.22 to 0.51) but there was no evidence of benefit among patients in other strata (PFS HR, 0.81; 80% CI, 0.60 to 1.09). The following grade ≥ 3 hematology toxicities were more frequent in the CE+V arm than the CE+P arm: CD4 lymphopenia (8% v 0%; P = .06) and neutropenia (49% v 32%; P = .08), but treatment delivery was comparable.
conclusionThe addition of veliparib to frontline chemotherapy showed signal of efficacy in patients with ES-SCLC and the study met its prespecified end point.
