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

purposeThe aim of this study was to analyse the correlation between (18)F-labelled 3'-deoxy-3'-fluorothymidine ((18)F-FLT) PET/CT proliferation images and tumour angiogenesis as reflected by intratumoral microvessel density (MVD) in non-small-cell lung cancer (NSCLC) to provide a noninvasive method to predict the response to antiangiogenic therapy.

methodsA total of 68 patients with proven or suspected NSCLC underwent FLT PET/CT scans followed by surgery. PET/CT images were compared with pathology. Tumour proliferation was evaluated in terms of a Ki-67 labelling index (Ki-67 LI). MVD was determined using an anti-CD31 mAb (CD31-MVD), anti-CD34 mAb (CD34-MVD) and an anti-CD105 mAb (CD105-MVD) for each resected tumour.

resultsTumour FLT maximum standardized uptake values (SUVmax) were significantly correlated with the Ki-67 LI and CD105-MVD (r = 0.550 and 0.633, P = 0.000 and 0.000, respectively), but were only marginally correlated with the CD31-MVD and CD34-MVD (r = 0.228 and 0.235, P = 0.062 and 0.054, respectively). The FLT PET false-negative patients had a longer median survival time than the FLT PET true-positive patients (log rank test, P = 0.012). The patients with a lower CD105-MVD had a longer median survival time than those with a higher CD105-MVD (P = 0.046), while patients with a lower CD31-MVD and CD34-MVD did not have a longer median survival time than those with a higher value (P = 0.438 and 0.187, respectively).

conclusionFLT PET/CT imaging correlated with tumour angiogenesis as reflected by CD105-MVD and prognosis, and may be helpful in assessing antiangiogenic therapy of NSCLC.
