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

BACKGROUND & PURPOSE: We investigated clinical and genetic factors associated with severe radiation-induced lymphopenia (RIL) in a randomized clinical trial of photon vs. proton radiation, with chemotherapy, for non-small cell lung cancer.

methodsXRCC1 rs25487 was genotyped in lymphocytes from serial peripheral blood samples. Severe RIL was defined as absolute lymphocyte count (ALC) < 0.3 × 10

resultsUnivariate analysis of the 178 patients in this analysis showed that older age, larger tumors, higher lung V5 and mean lung dose, and higher heart V5 and mean heart dose were associated with severe RIL during treatment (P < 0.05). The XRCC1 rs25487 AA genotype was also associated with increased risk of severe RIL during treatment (AA vs. others: hazard ratio [HR] = 1.665, 95% confidence interval [CI] 1.089-2.500, P = 0.018). Multivariate analyses showed that older age (HR = 1.031, 95% CI 1.009-1.054, P = 0.005), lung V5 (HR = 1.039, 95% CI 1.023-1.055, P < 0.0001), and AA genotype (AA vs. others, HR = 1.768, 95% CI 1.165-2.684, P = 0.007) were independently associated with higher incidence of severe RIL. These three risk factors (age ≥ 56 years, lung V5 ≥ 51% and XRCC1 rs25487 AA) distinguished patients at different risk of developing severe RIL (P < 0.0001).

conclusionsAge, lung V5 and XRCC1 rs25487 AA were all linked with risk of severe RIL. Our predictive risk model may be helpful for identifying patients at high risk of severe RIL so that treatment can be modified.
