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

purposeTo analyze the association of patient- and treatment-related factors with the onset of radiation pneumonitis in a homogeneously treated cohort of patients suffering from small cell lung cancer (SCLC). PATIENTS AND

methods242 patients with SCLC staged as limited disease, who had been treated with chemotherapy and three-dimensional conformal radiotherapy, were retrospectively analyzed. Pneumonitis was defined by typical symptoms and radiographic findings and judged clinically relevant, if drug administration and hospitalization were necessary. Patient- (age, gender, smoking history, performance status, tumor localization, benign lung disease) and treatment-related parameters (V(10)-V(40), mean lung dose [MLD]) were analyzed using χ(2)-tests for categorical parameters and logistic regression for continuous variables.

results33 patients (13.6%) developed a clinically relevant pneumonitis, of whom three patients died. All cases of pneumonitis developed within 120 days. None of the patient-related parameters correlated significantly with the onset of pneumonitis. Considering treatment-related parameters, a significant correlation of V(30) in regard to total lung and V(40) in regard to ipsilateral, contralateral and total lung to the risk of pneumonitis was found. So, the estimated risk of a clinically relevant pneumonitis increased from 10% given a V(30) of 13% to 30% given a V(30) of 35%. In contrast, no significant correlation was found for V(10) and V(20) and only a trend for MLD.

conclusionIn this series, high-dose radiation volume parameters, i.e., V(30) and especially V(40), were identified as the most important factors for the development of radiation pneumonitis. Low-dose radiation volume parameters and clinical parameters played an inferior role in predicting the pneumonitis risk.
