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: The tumor shrinkage rate in patients with locally advanced cervical cancer after external beam radiotherapy varies widely, and simple pretreatment predictors are lacking. The lymphocyte-to-monocyte ratio (LMR) is a routine blood marker reflecting inflammatory and immune status; however, its association with short-term radiotherapy response in cervical cancer remains unclear. Methods: We retrospectively enrolled 247 patients with locally advanced cervical cancer who underwent radical external-beam radiotherapy between April 2020 and April 2025. LMR was calculated from pretreatment blood counts, with extreme values winsorized. The primary outcome was the continuous tumor shrinkage rate and the secondary outcome was a marked response (≥70% shrinkage). Multivariable linear and logistic regressions were used to assess the LMR-shrinkage association, adjusting for age, body mass index, International Federation of Gynecology and Obstetrics stage, pretreatment maximum tumor diameter, lymph node metastasis, concurrent chemoradiotherapy, and radiotherapy dose. Subgroup and sensitivity analyses were also performed. Results: In the multivariate analysis, each unit increase in LMR was associated with a 0.018 absolute increase in shrinkage rate (95% confidence interval (CI)], 0.001-0.036; P = 0.0477). The odds ratio for achieving a marked response was 1.117 per unit increase in LMR (95% CI: 1.002-1.356, P = 0.0241). The LMR effect was consistent across subgroups and remained significant after adjusting for nutritional and oxidative stress markers. The restricted cubic splines exhibit linearity (P for nonlinearity = 0.098). Conclusion: A higher pretreatment LMR was independently associated with better tumor shrinkage after external beam radiotherapy in patients with locally advanced cervical cancer. This readily available hematological marker may help identify patients who are likely to benefit from radiotherapy, although prospective validation is warranted.
