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

purposeMolecular testing in non-small cell lung cancer (NSCLC) aids in identifying oncogenic alterations. The aim of this study was to compare the rates of detection of oncogenic alterations and responsiveness to epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) according to EGFR mutation status as determined by peptide nucleic acid (PNA) clamping or direct sequencing (DS). MATERIALS AND

methodsWe performed a systematic literature search using MEDLINE, EMBASE, and the Cochrane Central Register. Data from included studies were pooled to yield summary sensitivity, specificity, positive and negative likelihood ratios, diagnostic odds ratio, and receiver operating characteristic curves. A meta-regression analysis was conducted to identify potential sources of heterogeneity between selected studies.

resultsWe identified 10 studies comprising 924 patients. Oncogenic alterations were detected in 340 of 924 cases (36.8%) with PNA clamping and in 250 of 924 (27.1%) with DS. The pooled sensitivities of PNA clamping and DS were 0.93 [95% confidence interval (CI): 0.90-0.95] and 0.69 (95% CI: 0.64-0.73), respectively. According to meta-regression analysis, none of the covariates were found to be significant sources of heterogeneity. With respect to treatment responses to EGFR-TKIs, there was no significant difference therein between EGFR mutations detected by PNA clamping and DS (53.4% vs. 50.8%; risk ratio, 0.99; 95% CI 0.83-1.19; p=0.874).

conclusionWe demonstrated that PNA clamping has a higher sensitivity than DS for detecting oncogenic alterations in NSCLC. Our findings suggest that PNA clamping is a more useful method for clinical practice.
