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
Background: Whole-brain radiotherapy is associated with neurocognitive decline and decreased quality-of-life (QOL) among survivors of brain metastasis. Hippocampal-avoidance whole-brain radiotherapy (HA-WBRT) has shown advantage in delaying or preventing the neurocognitive decline while maintaining disease control. This study was done to assess the benefits and feasibility of HA-WBRT in patients with cerebral metastasis in terms of preservation of neurocognitive function and quality of life. Materials and methods: 27 patients with brain metastasis treated by HA-WBRT and having the records of detailed neurocognitive-assessments were analysed from the database of our hospital. The patients were treated with HA-WBRT to a total dose of 30 Gy in 10 fractions with LINAC based IMRT using the VMAT technique. Cognitive function assessment was carried out using "Examination of the Cognitive Functions" scale provided by Bangur-Institute-of-Neurosciences, Kolkata, 2 weeks prior to radiotherapy and post-treatment two-monthly up to 6 months followed by every 3 months till the last follow up. QOL was assessed at the same interval using the Functional Assessment of Cancer Therapy with Brain Subscale (FACT-BR). Follow-up was done till the date of death. Results: Mean relative cognitive decline percentage decreased over subsequent follow-up visits and was 13% (SD ± 6%), 5% (SD ± 5%), 5% (SD ± 9%) and 2% (SD ± 12%) at 2 months, 6 months, 9 months and 12 months, respectively (p ≤ 0.05). Statistically significant improvement was seen in the mean social-wellbeing (SWB) parameter of QOL (8%. ± 13%, 12%. ± 16%, 7%. ± 20%, no change at 2 months, 4 months, 6 months and 9 months, respectively) (p ≤ 0.05). Mean relative decline in the Emotional-Well Being (EWB) parameter was significant only at 12 months and was 20% (SD ± 35%) (p = 0.04). Mean FACT-BR total Score showed a slight decrease till 9 months from baseline, and then showed a slight improvement up to 12 months. Conclusion: HA-WBRT is feasible with LINAC-based IMRT using the VMAT technique and beneficial to the patients in preserving neurocognitive function and quality of life without compromising disease control.
