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.
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
objectiveThis study assessed the impact of prophylactic para-aortic lymph node (PALN) irradiation with extended-field radiotherapy (EF-RT) in individuals with locally advanced cervical cancer. The principal objective was overall survival (OS), whereas the secondary outcomes included PALN metastases, full remission, pelvic recurrence, distant metastasis, and mortality attributable to cervical cancer.
methodsA thorough search was performed in Pubmed, Cochrane Central Register of Controlled Trials, and Science Direct in November 2023, following PRISMA procedures. Randomized trials comparing EF-RT to pelvic-only radiation for locally advanced cervical cancer without PALN involvement were incorporated. A meta-analysis was conducted using RevMan software to evaluate the Hazard Ratio (HR) for overall survival (OS) and the Odds Ratio (OR) for additional outcomes.
resultSix Randomized Controlled Trials involving 1,028 patients (508 in EF-RT group and 520 in pelvic-only radiotherapy group) were analyzed. EF-RT significantly reduced para-aortic lymph node metastases compared to standard pelvic radiotherapy (OR = 0.23, 95% CI [0.12;0.44], p-value<0.00001, 4 studies), but not significantly improve overall survival (HR = 0.97, 95% CI [0.82;1.16], p-value>0.05, 6 studies) nor other outcomes. EF-RT was also associated with increased gastrointestinal but not urological or gynecological complications.
conclusionEF-RT as a prophylactic treatment for cervical cancer patients with negative PALN metastasis significantly reduces para-aortic lymph node metastatic events, nonetheless, it is improbable to offer any advantages regarding overall survival, managed pelvic illness, or distant metastatic sites. Furthermore, its adverse effects on gastrointestinal problems were observed to exceed those of conventional pelvic irradiation, necessitating further consideration.
