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
Objective: This study aimed to examine the relationship between L3 Skeletal Muscle Index (L3SMI) and the incidence and severity of chemotherapy-induced peripheral neuropathy (CIPN) in patients with malignant tumors treated with nab-PTX (albumin-bound paclitaxel) monotherapy or in combination with cisplatin or carboplatin. Methods: This study included 52 patients with complete clinical data. The patients' baseline demographics, disease characteristics, body composition, PG-SGA scale and chemotherapy regimens,was evaluated prior to chemotherapy initiation. Blood samples were collected within 1 hour following the final nab-PTX dose. CIPN was assessed before the third chemotherapy cycle. Patients receiving nab-PTX doses on day 1 were categorized into Group A (n = 36), while those receiving doses on days 1 and 8 were assigned to Group B (n = 16). Group A was further divided into the sarcopenia subgroup (A1) and the non-sarcopenia group (A2), while Group B was divided into the sarcopenia subgroup (B1) and the non-sarcopenia subgroup (B2). The relationship between L3SMI, CIPN incidence and severity were analyzed, and the impact of L3SMI on blood drug concentrations was also investigated. Results: The pathological types of enrolled patients included: lung cancer, esophageal carcinoma, cervical cancer, and ovarian cancer. The incidence of CIPN ≥ B grade was significantly higher in sarcopenia subgroups compare with non-sarcopenia in Group A (A1 vs. A2, Conclusion: Sarcopenia significantly increases the incidence and severity of CIPN in patients undergoing nab-PTX-based chemotherapy. This association may be attributed to the effectively higher dose of nab-PTX per kilogram of lean body mass in patients with sarcopenia, despite the absence of a direct correlation between L3SMI and measured blood drug concentrations. These findings highlight the importance of body composition assessment prior to chemotherapy, as patients with sarcopenia may require enhanced monitoring for CIPN or individualized dosing considerations.
