1 · What the graph read from 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.

2 · The registry

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

backgroundCisplatin-based adjuvant chemotherapy is the standard of care for patients with completely resected non-small cell lung cancer (NSCLC). However, carboplatin-based regimens are often selected in clinical practice for patients considered unsuitable for cisplatin, although evidence regarding their long-term survival outcomes remains limited.

methodsWe conducted a meta-analysis to compare survival outcomes between cisplatin-based and carboplatin-based adjuvant chemotherapy in patients with completely resected NSCLC. PubMed and the Cochrane CENTRAL database were searched for relevant studies published up to April 7, 2026. Eligible studies included randomized and observational studies reporting hazard ratios (HRs) for overall survival (OS) and/or recurrence-free survival (RFS).

resultsA total of eight studies involving 2269 patients were included. The pooled HRs for OS and RFS indicated no significant differences between the two regimens (OS: HR, 1.08; 95% CI 0.92-1.26; RFS: HR, 0.92; 95% CI 0.71-1.20). A sensitivity analysis limited to randomized controlled trials also demonstrated no significant differences between the two regimens (OS: HR, 0.95; 95% CI 0.60-1.51; RFS: HR, 0.96; 95% CI 0.59-1.58).

conclusionsCarboplatin-based adjuvant chemotherapy may be considered as an alternative in cisplatin-unfit patients with completely resected NSCLC.
