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

backgroundThe Affordable Care Act (ACA) enabled states to expand Medicaid eligibility, extending coverage to millions, particularly in California. While Medicaid expansion has been linked to earlier diagnoses in several cancers, its impact on thyroid cancer-a slow-growing malignancy lacking formal screening-remains unclear.

objectiveTo assess whether Medicaid expansion influenced thyroid cancer stage at presentation.

methodsA retrospective cohort study using SEER data (2009-2020) compared adults aged 18-64 diagnosed with thyroid cancer in California (expansion) and Texas (non-expansion). Difference-in-differences logistic regression evaluated stage changes pre- (2009-2013) and post- (2016-2020) expansion, excluding a 2014-2015 washout period.

resultsAmong 63,073 patients, no significant difference in stage at diagnosis was observed between states. Estimates for localized, regional, and distant disease changes ranged from -1.3 ​% to 1.1 ​% (all 95 ​% CIs included zero).

conclusionMedicaid expansion was not associated with a significant shift in thyroid cancer stage at presentation.
