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
Introduction: Metastatic colorectal cancer (mCRC) poses significant challenges in low- and middle-income countries (LMICs) due to limited access to comprehensive care. This study aims to analyze the clinical characteristics, treatment patterns, and outcomes of patients with metastatic colorectal cancer (mCRC) at a single tertiary care center in Pakistan. Materials and Methods: A retrospective cross-sectional study was conducted on 141 patients diagnosed with mCRC at the Aga Khan University Hospital (AKUH) between January 2020 and December 2022. Data on demographics, tumor characteristics, metastasis patterns, treatment modalities, and outcomes were extracted from electronic medical records. Descriptive statistics and survival analysis were performed. Results: The mean age of the cohort was 51 years (SD ± 17.43), with 56.7% male patients. The study included patients from all over Pakistan, with the majority residing in Sindh (71.1%). Additionally, 8.5% of patients were from outside Pakistan. Rectum (27.5%) and sigmoid colon (20.4%) were the predominant tumor locations. Adenocarcinoma was the most common histological type (90.1%). Liver-only metastases were observed in 27.5% of patients, with 48.2% presenting multisite metastases. Chemotherapy was administered to 74.6% of patients, with FOLFOX being the most common regimen (38.3%). Primary tumor resection was performed in 43.7% of cases, and metastatic lesion resection in 7.7%. Fragmented care was observed, with 21.4% of patients receiving diagnostic or therapeutic interventions outside AKUH as well. The median time from diagnosis of metastasis to death was 4.9 months (IQR: 1.1-9.3). Conclusion: mCRC patients in Pakistan present with a younger age, higher prevalence of multisite metastases, and limited access to advanced multimodal treatments compared to HICs. These findings underscore the need for tailored public health initiatives, including age-specific screening programs, improved diagnostic and treatment infrastructure, and enhanced access to advanced therapies to improve outcomes in LMICs.
