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
objectivesThe project is designed to compare the clinical efficacy and adverse events resulting from immune checkpoint inhibitors (ICIs) plus chemotherapy and chemotherapy alone in patients with small cell lung cancer (SCLC).
methodsPubMed Database and ClinicalTrials.gov were both searched to identify randomized controlled clinical trials for assessing ICIs in all-stage SCLC. After screening in strict accordance with the inclusion and exclusion criteria, eligible studies were evaluated in regard to the population, intervention, comparator, outcome as well as study design (PICOS) pattern. Furthermore, primary endpoints of these randomized controlled trials (RCTs) included overall survival (OS), progression-free survival (PFS) and complete/objective response rate (CRR/ORR). Statistical analyses were realized via Review Manager Version 5.3 Software.
resultsCompared with the chemotherapy alone group, the ICIs plus chemotherapy group significantly improved with respect to such indicators as OS (hazard ratio (HR) = 0.82, 95% CI 0.74-0.90, P < 0.0001), PFS (HR = 0.80, 95% CI 0.74-0.87, P < 0.00001) and ORR (64.7% versus 59.1%). According to the safety analysis, the incidence of treatment-related adverse events (trAEs) at all grades was higher in ICIs plus chemotherapy group (OR = 1.59, 95% CI 1.20-2.10, P = 0.001), bearing no statistical significance at grade 3 or above (OR = 1.21, 95% CI 0.99-1.49, P = 0.07).
conclusionsThe combination of ICIs and chemotherapy witnessed better anti-neoplastic efficacy for SCLC. Moreover, the incidence of trAEs at all grades was elevated in ICIs plus chemotherapy group, with little discrepancy in both groups at grade 3 or above.
