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

backgroundFor patients with non-small cell lung cancer the TNM staging system and other conventional prognostic factors fail to predict accurately the outcome of treatment and survival. This study attempts to determine the prognostic value for survival of the proportions of CD4+ lymphocytes in the pleural cavity (PLY) of patients with resectable non-small cell lung cancer.

methodsLymphocytes in the pleural cavity separated from 51 patients with non-small cell lung cancer were examined by flow cytometry to measure the proportions of CD4+ PLY. Univariate and multivariate analyses were performed to assess the association between the proportion of CD4+ PLY and survival.

resultsThe 5 year survival rate of patients with percentage CD4+ PLY of < or = 30% was 84% whereas that of patients with %CD4+ PLY > 30% was 26.9%. The difference in survival between the %CD4+ PLY < or = 30% and %CD4+ PLY > 30% groups was significant (p < 0.0001). The %CD4+ PLY in those who survived for 5 years was significantly lower than that in the patients who died within 5 years (p < 0.0001). The difference in survival between patients with stage IA and IB lung cancer with %CD4+ PLY < or = 30% and those with %CD4+ PLY > 30% was also significant (p = 0.015). Multivariate analysis showed that the proportion of CD4+ PLY (hazard ratio = 6.9, 95% CI 0.045 to 0.47) and nodal status (hazard ratio = 22.7, 95% CI 0.006 to 1.806) are significant and independent prognostic factors for the survival of patients with lung cancer.

conclusionsThe proportion of CD4+ PLY may help to select patients who are likely to have a poorer prognosis after surgery and therefore may be suitable for consideration of adjuvant treatments. These results need confirmation in a larger prospective study.
