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

introductionThe prognostic relevance of gender is undetermined in patients with small-cell lung cancer (SCLC). Therefore, we investigated whether gender is a prognostic factor in a SCLC cohort after controlling for confounding factors. MATERIALS AND

methodsFifteen prognostic factors were classified into four groups (patient, stage migration, tumor, and treatment). The prognostic relevance of gender was evaluated using propensity score matching, Cox proportional hazards regression, and stepwise fashion adjustments.

resultsOf 591 patients with SCLC, 88 were women (14.9%). Women were more likely than men to have no history of smoking (48.9% vs. 2.0%, P < 0.001) and limited disease (48.9% vs. 37.8%, P = 0.050). Women had less progressive disease in M stage than men (52.3% vs. 62.8%, P = 0.031). Women had better survival than men in the entire cohort (median survival times [MSTs] and 95% confidence intervals [CIs]: 9.7 months and 7.8-11.6 for women, 8.0 months and 7.0-8.9 for men, log-rank P = 0.034) and in the matched cohort (MSTs and 95% CIs: 8.8 months and 5.8-11.8 for women, 5.9 months and 4.5-7.4 for men, log-rank P = 0.013). Female gender was a prognostic factor predicting better survival, even after stepwise and full adjustment with all prognostic variables (adjusted hazard ratios and 95% CIs: 0.51 and 0.34-0.77, P = 0.001 for entire cohort, 0.42 and 0.24-0.75, P = 0.003 for matched cohort).

conclusionsOur results confirmed that gender is an independent prognostic factor in patients with SCLC.
